What are the verb forms in English? I know that there are 12.

Check the graphic here and let me know what you think.

Are they the ones shown at the beginning?

auxiliary, gerunds, infinitives, irregular, linking, mood, auxiliary, participles, phrasal, causative, factitive, and sequence?

auxiliary is in there twice; delete one of them.

Also delete sequence.

Add passive and active.

Oops...I copied and pasted those from the website, hence those mistakes.

Thank you so much :)!

You're welcome. =)

In English grammar, there are not 12 verb forms, but rather 3 primary verb forms: the base form, the past form, and the past participle form. These three forms can be used to create different tenses and aspects in English.

To understand how these different forms are used, it's important to know the concept of regular and irregular verbs. Regular verbs follow a predictable pattern when forming their past and past participle forms, while irregular verbs do not follow a consistent pattern and must be memorized.

Here's how you can identify and form the verb forms:

1. Base Form: This is the simplest form of the verb, often referred to as the "infinitive." It does not show tense or person. For regular verbs, the base form is usually the same as the present form (e.g., walk, talk, eat). Irregular verbs, however, have unique base forms (e.g., go, have, be).

2. Past Form: This form indicates a completed action in the past. For regular verbs, the past form is usually created by adding "-ed" or "-d" to the base form (e.g., walked, talked, played). However, irregular verbs have specific past forms that need to be learned (e.g., went, had, was).

3. Past Participle Form: This form is used to create the perfect tenses and passive voice. For regular verbs, the past participle form is usually created by adding "-ed" or "-d" to the base form (e.g., walked, talked, played). Again, irregular verbs have unique past participle forms (e.g., gone, had, been).

By combining these three basic forms with helping verbs (e.g., be, have, will), English speakers can create a wide variety of verb tenses and aspects, such as present simple, past continuous, future perfect, and so on.

It's worth noting that some grammatical sources may refer to additional tenses, such as the present participle form (-ing) and the infinitive with "to" form (e.g., to walk, to talk). However, these forms are derivations of the base form and are not considered separate verb forms.

To summarize, although there may be more than 3 forms associated with verbs in English, the primary verb forms are the base form, past form, and past participle form.
