Demystifying Verb Conjugation: The Ultimate Guide

Unlocking the Secrets of English Verb Conjugation: Dive into forms, tenses, and irregular patterns with this ultimate guide for language learners.

Welcome back to the blog, language learners! Have you ever wondered why we say "I am" but "he is", or why "walk" becomes "walked" but "go" becomes "went"? The answer lies in a fundamental concept of grammar: conjugation.

The conjugation of a verb shows the various forms it assumes, either by inflection or by combination with parts of other verbs, to mark Voice, Mood, Tense, Number, and Person. To fully conjugate a verb, we must also include its infinitives and participles.

Let's break down the five pillars of verb conjugation to help you perfect your English sentences!

1. Person and Number

The golden rule of grammar is that a verb must agree with its subject in number and person. In English, verbs in their base present tense form are actually considered plural. To make a present tense verb singular, you must add an "-s" or "-es" to it. For example, in the simple present tense, the verb "speak" conjugates as "I speak", "You speak", and "We speak", but changes to "He speaks" for the third-person singular.

2. Tense

Conjugation also indicates the time of an action. Tense is that form of a verb which shows the time and the state of an action or event. By conjugating a verb, you can move it through time, from the Simple Present ("I speak") to the Present Continuous ("I am speaking"), all the way to the Future Perfect Continuous ("I shall/will have been speaking").

3. Voice

Conjugation changes depending on the Voice of the sentence. Voice is the function of a verb that expresses whether the subject is doing the action of the verb or receiving the action of the verb. Voice is always either active or passive.

4. Mood

Did you know verbs have moods? Mood is the mode or manner in which the action denoted by the verb is represented. A conjugated verb can be used to make a simple statement of fact, express a command, or even express a mere supposition (like "If I were you").

5. Regular vs. Irregular Verbs

How a verb conjugates depends heavily on what class it belongs to. English verbs are divided into two classes: regular and irregular.

• Regular verbs form their past tense and past participle by simply adding -d, -ed, or -t to the present form, without the vowel changing. For example: walk, walked, walked.

• Irregular verbs do not follow this set pattern. Instead, the vowel often changes and an -n or -e might be added (like begin, began, begun), or a -d or -t is added alongside a vowel change (like lose, lost, lost).

Conjugation in Action: The Verb "Love"

To see how all these pieces fit together, let's look at the complete conjugation of the verb love in the Simple Present tense, showing the differences in Person, Number, and Voice:

Active Voice (The subject performs the action):

• First Person: I love.

• Second Person: You love.

• Third Person Singular: He loves.

• Plural: They love.

Passive Voice (The subject receives the action):

• First Person: I am loved.

• Second Person: You are loved.

• Third Person Singular: He is loved.

• Plural: They are loved.

Mastering conjugation is the key to unlocking fluent, grammatically correct English. Keep practicing, and soon these verb transformations will become second nature!

The Five Structural Pillars of English Conjugation: Person, Number, Tense, Voice, and Mood, form the foundation of grammar structure by defining who acts, how many, when the action occurs, who receives it, and the action's reality.

Conjugation in English grammar refers to listing the various forms a verb assumes to show its exact grammatical role in a sentence. When you conjugate a verb, you are listing its singular and plural forms in a specific tense.

A verb changes its form—either by inflection (altering the word itself, such as adding an ending) or by combining with auxiliary (helping) verbs—to mark five key things: Voice, Mood, Tense, Number, and Person.

Here is a detailed breakdown of how conjugation works in English:

1. The Building Blocks: The Five Forms of Verbs

To conjugate a verb across all tenses, English relies on five primary forms of the main verb:

• Base Form / Infinitive: The original form of the verb, often preceded by "to" (e.g., to arise, to play).

• Present Form (with s/es/ies): Used for third-person singular subjects in the present tense (e.g., arises, plays, tries).

• Past Form: Indicates a simple past action (e.g., arose, played).

• Past Participle: Used with auxiliary verbs for perfect tenses and passive voice (e.g., arisen, played).

• Present Participle ("-ing" form): Created by adding "-ing" to the base form, used for continuous/progressive tenses (e.g., arising, playing).

  
  

2. Person and Number

Conjugation changes a verb to agree with its subject's Person (First: I/we, Second: you, Third: he/she/it/they) and Number (Singular or Plural).

• In modern English, verbs have lost almost all of their unique endings for person and number, except for the third-person singular in the present tense, which requires adding an -s, -es, or changing a -y to -ies (e.g., I catch vs. He catches).

• The Exception: The most irregular verb in English is the verb to be, which is conjugated entirely differently depending on person and number (I am, you are, he is, we are, they are).

  
  

3. Tense

Conjugation shows the time of an action (Past, Present, or Future). While simple tenses might just alter the base verb, progressive (continuous) and perfect tenses are conjugated by adding auxiliary verbs like be, do, or have.

4. Regular vs. Irregular Conjugation

• Regular Verbs: Conjugate their past tense and past participle forms simply by adding -d, -ed, or -t to the base form without changing the internal vowel (e.g., look, looked, looked).

• Irregular Verbs: Do not follow a set pattern. They often conjugate by changing the internal vowel and adding an -n or -e (e.g., begin, began, begun), or completely changing form (e.g., go, went, gone).

  
  

5. Voice and Mood

Conjugation also indicates Voice (whether the subject performs the action in the Active Voice or receives the action in the Passive Voice) and Mood (whether the verb is stating a fact, giving a command, or expressing a hypothetical situation).

Example: Conjugation of the Verb "Love"

To see conjugation in action, here is how the verb love is conjugated in the Simple Present tense, marking differences in Person, Number, and Voice:

Active Voice (The subject performs the action)

• First Person Singular: I love

• Second Person: You love

• Third Person Singular: He/She/It loves

• Plural (First/Second/Third): We / You / They love

Passive Voice (The subject receives the action)

• First Person Singular: I am loved

• Second Person: You are loved

• Third Person Singular: He/She/It is loved

• Plural (First/Second/Third): We / You / They are loved

Understanding English Morphology: Learn how to connect subjects to verbs, focusing on the third-person singular rule of adding -s or -es in the present tense to form sentences like "The boy plays" and "The bus arrives."

English Morphology!

Welcome to the intriguing realm of English morphology! As a teacher of English, I assure you that irregular verbs are among the most historically significant aspects of the English language. They are linguistic "fossils"—traces of Old English strong verbs that altered their internal vowels (a process known as ablaut), instead of merely adding the usual dental suffixes -ed or -d.

Below is a detailed Master List of the most vital and frequently used irregular English verbs. I have organized this precisely into the five columns.

In this table, you will observe three main patterns of irregularity:

English strong verbs that changed their internal vowels (a process called ablaut), rather than simply adding the standard dental suffixes -ed or -d.

Below is a comprehensive Master List of the most essential and commonly used irregular English verbs. I have formatted this strictly into the five columns.

In this table, you will notice three primary patterns of irregularity:

1.   Zero-derivation (No-change) verbs: All three principal parts are identical (e.g., cut, put, set).

2.   Two-part identical verbs: Two of the forms are the same (e.g., sit / sat / sat or beat / beat / beaten).

3.   Fully distinct verbs: All three forms are different (e.g., ring / rang / rung).

I have also included regional and stylistic variations, such as the British English preference for -t endings (learnt, burnt) versus the American English preference for regular -ed endings (learned, burned), as well as American variations like dove and gotten.

Understanding Voice and Mood in English Grammar: This diagram illustrates how active and passive voices shift focus between the doer and receiver, while mood—indicative, imperative, and subjunctive—conveys different realities and intentions, from facts to hypothetical wishes.

Professor's Observations on Challenging Irregularities:

• Lay vs. Lie: The transitive verb lay (meaning to place or put down) takes an object and conjugates as lay / laid / laid. The intransitive verb lie (meaning to recline) takes no object and conjugates as lie / lay / lain. Notice how the past tense of lie is exactly the same word as the present tense of lay—a classic trap for English learners! (And don't forget the regular verb lie meaning to tell an untruth, which is lie / lied / lied).

  
  

• The "Read" Anomaly: The verb read looks identical in its V1, V2, and V3 forms, but it undergoes a vowel shift in pronunciation. While the base form is pronounced with a long "ee" sound (/ri:d/), the past and past participle forms are pronounced like the color "red" (/red/).

  
  

• Spelling Nuances in V4 and V5: Pay close attention to the mechanics of the present participle (V5). Verbs ending in a single stressed vowel followed by a consonant double that final consonant (run $\rightarrow$ running, sit $\rightarrow$ sitting). Verbs ending in a silent 'e' drop it (write $\rightarrow$ writing), and verbs ending in 'ie' change the 'ie' to 'y' to prevent a triple-vowel collision (lie $\rightarrow$ lying).

Let us pull back the curtain and dive deeper into the linguistic mechanics and historical quirks that make English irregular verbs so fascinating.

As a linguistics professor, I often tell my students that irregular verbs are not just random exceptions designed to torture language learners; they are living fossils of how the English language evolved.

Here is a breakdown of the core grammatical mechanics behind these verbs:

1. The Historical Divide: "Strong" vs. "Weak" Verbs

To understand irregular verbs, we must look at their historical ancestors. Historically, verbs were classified into two main categories:

• Weak Verbs: These are verbs that form their past tense by adding a dental suffix (an ending with a "d" or "t" sound) such as -ed, -d, or -t. Examples include sell/sold, burn/burnt, and lend/lent. Today, we generally refer to these as Regular Verbs.

• Strong Verbs: These verbs form their past tense purely by changing their internal vowel—a process known as ablaut or vowel gradation—without adding an ending,. Examples include find/found, bear/bore, and abide/abode. Today, these make up the bulk of our Irregular Verbs,.

• 
  

2. The Three Modern Patterns of Irregularity

In modern English grammar, we classify irregular verbs into three distinct types based on how their principal parts (Base Form, Past Tense, and Past Participle) change,:

• Type 1 (All three forms are the same): These verbs undergo zero derivation. Examples include cut - cut - cut, cost - cost - cost, and put - put - put,,.

• Type 2 (Two of the three forms are the same): In this group, the past tense and past participle are usually identical. Examples include sit - sat - sat, catch - caught - caught, and feel - felt - felt,. This also includes verbs where the base form and past participle are identical, such as come - came - come,.

• Type 3 (All three forms are different): These are the true descendants of the old strong verbs. Examples include ring - rang - rung, drink - drank - drunk, and go - went - gone,,.

  
  

3. Fascinating Spelling and Pronunciation Quirks

Sometimes, the mechanics of irregular verbs play tricks on our eyes and ears:

• The "Read" Anomaly: The verb read looks identical across all three forms (read - read - read), making it look like a Type 1 verb. However, it undergoes a vowel shift in pronunciation. The base form is pronounced with a long "ee" sound (/ri:d/), but the past and past participle forms are pronounced like the color "red" (/red/).

• Phonetically Regular, Orthographically Irregular: Verbs like lay and pay are actually pronounced perfectly regularly in the past tense (as if they were simply layed and payed), but their spelling is irregular (laid and paid),.

• The Lie vs. Lay Trap: This is perhaps the most notorious confusion in English grammar. Lay is a transitive verb (meaning to place something down) and must take a direct object,,. It conjugates as lay / laid / laid,. Lie is an intransitive verb (meaning to recline) and conjugates as lie / lay / lain,,. The massive confusion stems from the fact that the past tense of lie (lay) is spelled and pronounced exactly the same as the present tense of lay,.

  
  

4. Fossilized Adjectival Participles

Finally, one of the most interesting mechanics of irregular verbs is that some possess an alternative past participle ending in -en that survives today almost exclusively as an adjective.

• For instance, we use the standard past participle to say, "The ship has sunk" or "The iron has melted".

• However, we use the older -en form as an adjective before a noun: "a sunken ship," "a shrunken head," "molten iron," or "a drunken spectator",,.

These mechanical quirks are exactly what make English such a rich and layered language! Do you have any specific verbs you find particularly puzzling, or would you like to explore another area of syntax?

Conjugation Spelling Rules for Verbs

Welcome to the "Spelling Logic" approach to irregular verbs! Rote memorization of hundreds of irregular verbs is tedious and inefficient. By analyzing their morphological and orthographic patterns, we can group them into logical spelling categories.

Here is your comprehensive guide to irregular English verbs, categorized by their distinct spelling transformation rules.

1. The '1-1-1' Doubling Rule

This group features verbs that end in a single consonant, preceded by a single vowel, in a single stressed syllable.

V1 (Base)	V2 (Simple Past)	V3 (Past Participle)	V4 (3rd Person Singular)	V5 (Present Participle)
Begin	Began	Begun	Begins	Beginning
Cut	Cut	Cut	Cuts	Cutting
Forget	Forgot	Forgotten	Forgets	Forgetting
Get	Got	Got / Gotten	Gets	Getting
Hit	Hit	Hit	Hits	Hitting
Run	Ran	Run	Runs	Running
Sit	Sat	Sat	Sits	Sitting
Spin	Spun	Spun	Spins	Spinning
Swim	Swam	Swum	Swims	Swimming

• Spelling Tip: The "1-1-1 Rule" (one syllable, one short vowel, one ending consonant) dictates that you must double the final consonant before adding a suffix that begins with a vowel (like -ing). This creates a "sound barrier" that prevents the vowel from becoming long. In words with more than one syllable (like be-GIN or for-GET), the rule only applies because the stress falls on that final syllable.

Understanding the Morphological Math of Regular Verbs: Explore the '1-1-1 Doubling Rule', the 'Silent E Drop', and the 'Y to I Change' to master verb patterns effortlessly.

2. The Silent 'E' Drop

This group features verbs that end in an unpronounced (silent) 'e'.

V1 (Base)	V2 (Simple Past)	V3 (Past Participle)	V4 (3rd Person Singular)	V5 (Present Participle)
Arise	Arose	Arisen	Arises	Arising
Choose	Chose	Chosen	Chooses	Choosing
Come	Came	Come	Comes	Coming
Drive	Drove	Driven	Drives	Driving
Give	Gave	Given	Gives	Giving
Hide	Hid	Hidden	Hides	Hiding
Take	Took	Taken	Takes	Taking
Write	Wrote	Written	Writes	Writing

• Spelling Tip: When you add a suffix that starts with a vowel (like -ing), the silent 'e' is dropped because the new vowel takes over the job of making the internal vowel "long". However, when you add a suffix starting with a consonant (like the -s for the 3rd person singular), the silent 'e' must be kept.

3. The 'Y' to 'I' Shift (and 'IE' to 'Y')

This group focuses on the tricky orthographic rules surrounding the letter 'y' at the end of verbs.

V1 (Base)	V2 (Simple Past)	V3 (Past Participle)	V4 (3rd Person Singular)	V5 (Present Participle)
Fly	Flew	Flown	Flies	Flying
Cry*	Cried	Cried	Cries	Crying
Try*	Tried	Tried	Tries	Trying
Lie	Lay	Lain	Lies	Lying
Tie*	Tied	Tied	Ties	Tying

*While 'cry', 'try', and 'tie' are technically regular in their past tense forms, they are included here as they perfectly illustrate the spelling shifts of this category.

• Spelling Tip: If a verb ends in a consonant + 'y', you must change the 'y' to an 'i' before adding '-es' for V4. However, you keep the 'y' when adding -ing (V5) because English spelling hates having two 'i's next to each other (we avoid fliing). Conversely, if a word already ends in '-ie' (like lie), it swops the 'ie' to a 'y' before adding -ing for the exact same reason.

Understanding Vowel Shifts and Zero-Derivation: This image illustrates the historical linguistic process of ablaut, highlighting how certain verbs like "sing" and "drink" change their internal vowels to indicate tense. It contrasts this with zero-derivation, where verbs such as "put" and "set" remain unchanged due to their Old English origins.

4. The Vowel Shift Patterns

These verbs do not use dental suffixes (-ed/-d) for their past tenses. Instead, they change their internal vowels through a historical process known as ablaut.

V1 (Base)	V2 (Simple Past)	V3 (Past Participle)	V4 (3rd Person Singular)	V5 (Present Participle)
Begin	Began	Begun	Begins	Beginning
Drink	Drank	Drunk	Drinks	Drinking
Ring	Rang	Rung	Rings	Ringing
Sing	Sang	Sung	Sings	Singing
Spring	Sprang	Sprung	Springs	Springing
Blow	Blew	Blown	Blows	Blowing
Grow	Grew	Grown	Grows	Growing
Know	Knew	Known	Knows	Knowing
Throw	Threw	Thrown	Throws	Throwing

• Spelling Tip: Notice the distinct internal vowel patterns here! The first half perfectly follows the i-a-u pattern for V1, V2, and V3. The second half follows the o-e-o(wn) pattern. Recognizing these phonetic and spelling shifts allows you to master these "strong" irregular verbs in predictable batches rather than one by one.

Understanding the "No-Change Constants": Insights into the orthographic consistency of verbs like "read," with identical forms but different pronunciations across tenses, alongside clarifications on "lay" vs. "lie" usage.

5. The No-Change Constants

This group undergoes "zero-derivation" for their past tense forms. V1, V2, and V3 are orthographically identical.

V1 (Base)	V2 (Simple Past)	V3 (Past Participle)	V4 (3rd Person Singular)	V5 (Present Participle)
Burst	Burst	Burst	Bursts	Bursting
Cost	Cost	Cost	Costs	Costing
Cut	Cut	Cut	Cuts	Cutting
Let	Let	Let	Lets	Letting
Put	Put	Put	Puts	Putting
Read	Read	Read	Reads	Reading
Set	Set	Set	Sets	Setting
Shut	Shut	Shut	Shuts	Shutting
Spread	Spread	Spread	Spreads	Spreading

• Spelling Tip: While the base, past, and past participle forms never change their spelling, pay close attention to V5! Because many of these verbs are short, single-syllable words ending in a consonant, they frequently trigger the 1-1-1 Doubling Rule in their present participle forms (e.g., letting, putting, cutting). Also, note the anomaly of Read: it belongs in this spelling category because its letters never change, but its pronunciation radically shifts from a long "ee" in V1 to a short "eh" in V2/V3.

Here are 40 Frequently Asked Questions (FAQs) based on the rules and nuances of verb conjugation, drawing from the provided sources and our conversation history:

Basic Conjugation Concepts

1. What does "conjugation" mean in English grammar? 

Conjugation refers to the different forms a verb assumes to show its exact grammatical role in a sentence, changing to indicate Tense, Voice, Mood, Person, and Number.

2. What are the primary forms a verb takes when conjugated? 

A verb typically has five primary forms: the Base Form (Infinitive), the Present Form (Third-Person Singular), the Past Form, the Past Participle, and the Present Participle.

3. What is the "Base Form" of a verb? 

The base form is the original, unconjugated form of the verb, often preceded by the word "to" (e.g., to play, to ask).

4. How does conjugation show "Person"? 

Verbs must agree with the subject's perspective: First Person (I/we), Second Person (you), or Third Person (he/she/it/they).

5. How does conjugation show "Number"? 

Conjugation changes depending on whether the subject is singular (one) or plural (more than one). For example, "is" is used for singular subjects, while "are" is used for plural subjects.

6. What is the most irregularly conjugated verb in English? 

The verb "to be" is the most irregular because it completely changes form based on person and number (e.g., I am, you are, he is, we are, they are).

Regular and Irregular Verbs

7. What is a regular verb?

Regular verbs are verbs that form their past tense and past participle simply by adding "-d", "-ed", or "-t" to the base form (e.g., live $\rightarrow$ lived, talk $\rightarrow$ talked).

8. What is an irregular verb?

Irregular verbs do not follow standard suffix rules for their past forms. Instead of adding "-ed", they often change their internal vowels or change forms completely (e.g., go $\rightarrow$ went $\rightarrow$ gone).

9. Are there irregular verbs that never change their spelling?

Yes, some irregular verbs undergo zero-derivation, meaning their base, past, and past participle forms are spelled identically (e.g., cut, put, read, set).

10. How is the verb "read" conjugated? 

While "read" does not change its spelling in its past and past participle forms, it changes its pronunciation from a long "ee" sound in the present to a short "eh" sound in the past.

11. How do you conjugate the present participle for verbs ending in a silent 'e'? 

When adding the "-ing" suffix, you generally drop the silent 'e' at the end of the base verb (e.g., hope $\rightarrow$ hoping).

12. When do you double the consonant when conjugating the "-ing" form? 

According to the 1-1-1 rule, if a short verb ends in a single consonant preceded by a single short vowel, the final consonant is doubled (e.g., run $\rightarrow$ running).

13. How do you conjugate verbs ending in 'y' for the third-person singular? 

If a verb ends in a consonant + y, you change the 'y' to an 'i' and add '-es' (e.g., baby $\rightarrow$ babies, cry $\rightarrow$ cries).

Auxiliary Verbs and Tenses

14. What is an auxiliary verb?

Auxiliary (or helping) verbs combine with main verbs to conjugate different tenses, negative sentences, and questions. Common auxiliaries include be, do, does, did, is, am, are, have, has, and had.

15. How do you conjugate the present continuous tense? 

You combine the present auxiliary verb (is/am/are) with the present participle (-ing form) of the main verb.

16. How do you conjugate the past continuous tense? 

You combine the past auxiliary verb (was/were) with the present participle (-ing form) of the main verb.

17. How do you conjugate the present perfect tense?

You use the auxiliary "have" or "has" followed by the past participle (V3) of the main verb (e.g., "I have taken lunch").

18. How do you conjugate the past perfect tense? 

You use the auxiliary "had" combined with the past participle of the main verb (e.g., "He had gone").

19. What auxiliary verbs are used to conjugate the future tense? 

The simple future tense is conjugated by placing the auxiliary verbs "will" or "shall" before the base form of the main verb.

20. Can "have" be conjugated in the continuous "-ing" form? 

When "have" means possession, it is a stative verb and cannot be conjugated in the continuous form (e.g., "I have a car", not "I am having a car"). However, it can take the "-ing" form if it means experiencing or enjoying something (e.g., "They are having a party").

21. Why is the verb "have" sometimes conjugated as "had had"?

This happens in the past perfect tense when "have" acts as both the auxiliary verb and the main verb representing possession or consumption (e.g., "I had had my breakfast").

Forming Questions and Negatives

22. How do you conjugate a question in the simple present tense using the verb "be"? You invert the structure by moving the conjugated verb (is, am, or are) to the front of the subject (e.g., "Are you Canadian?").

23. How do you conjugate a question in the simple present for verbs other than "be"? You add the auxiliary verb "do" or "does" before the subject, and the main verb remains in its base form.

24. Do you add an "-s" to the main verb when asking a question in the third-person singular?

No. Once you use the auxiliary "does", the main verb must remain in its base form without an "-s" or "-es" (e.g., "Does he finish?", not "Does he finishes?").

25. How do you conjugate a negative simple present sentence? 

You add "do not" (or "doesn't" for the third-person singular) between the subject and the base form of the main verb.

26. How do you conjugate a negative sentence in the simple past tense? 

You use the auxiliary "did not" followed by the base form of the main verb.

27. Do you use the past form of the main verb in a simple past question?

No. When you use the past auxiliary "did" to form a question, the main verb reverts to its base form (e.g., "Did he write?", not "Did he wrote?").

28. How is a negative imperative conjugated? 

It is formed using "Do not" or "Don't" followed by the base infinitive of the verb (e.g., "Do not smoke in the airport").

Passive Voice Conjugation

29. What is Voice in conjugation?

Voice shows whether the subject of the sentence acts (Active Voice) or is acted upon (Passive Voice).

30. How do you conjugate a sentence in the passive voice? 

You take the object of the active sentence, make it the subject, and combine the appropriate tense of the auxiliary verb "be" with the past participle of the main verb.

31. How is the continuous passive voice conjugated? 

You insert the word "being" between the auxiliary "be" and the past participle of the main verb (e.g., "A letter is being written by him").

32. How is the perfect passive voice conjugated? 

You insert the word "been" between the auxiliary "have/has/had" and the past participle (e.g., "A book has been written by him").

Modals and Special Cases

33. What are modal auxiliary verbs?

Modals are verbs like can, could, may, might, shall, should, will, and would that express possibility, obligation, permission, or necessity.

34. Do modal verbs take an "-s" in the third-person singular present?

No, modal verbs do not change form or take an "-s" when used with singular subjects (e.g., "He can say").

35. How do you conjugate verbs after a modal auxiliary? 

The main verb that follows a modal auxiliary must always be in its base infinitive form, without "to" (e.g., "I shall play", "He must obey").

36. What is a "stative verb" and how does it affect conjugation?

Stative verbs express permanent states, senses, or functions of the mind (e.g., see, hear, know, and understand). They are rarely conjugated in continuous ("-ing") tenses.

37. How do you conjugate the verb "to be" for hypothetical or imaginary situations in the past?

For unreal past conditions or wishes, you use the subjunctive form "were" for all subjects, even singular ones (e.g., "Were I a king!", "Were she a bird!").

38. How is "used to" conjugated for negative past habits? It is conjugated with the auxiliary "didn't" and drops the "d" on "used," becoming "didn't use to" (or formally "used not to").

39. How do you conjugate verbs that follow "had better"? 

The phrase "had better" is used to give strong advice and is followed by the bare infinitive of the verb without "to" (e.g., "You had better stop gambling now").

40. Are gerunds a form of conjugation?

Yes, a gerund is the present participle form of a verb (adding "-ing") that functions grammatically as a noun within a sentence (e.g., "Swimming is a good exercise").
