Enum Constant Detail

BARE_INFINITIVE

public static final Form BARE_INFINITIVE

The bare infinitive is the base form of the verb.

GERUND

public static final Form GERUND

In English, the gerund form refers to the usage of a verb as a noun. For example, I like swimming. In more general terms, gerunds are usually formed from the base word with -ing added to the end.

IMPERATIVE

public static final Form IMPERATIVE

The imperative form of a verb is the one used when the grammatical mood is one of expressing a command or giving a direct request. For example, Close the door.

INFINITIVE

public static final Form INFINITIVE

The infinitive form represents the base form of the verb, with our without the particle to. For example, do and to do are both infinitive forms of do.

NORMAL

public static final Form NORMAL

Normal form represents the base verb. For example, kiss, walk, bark, eat.

PAST_PARTICIPLE

public static final Form PAST_PARTICIPLE

Most verbs will have only a single form for the past tense. However, some verbs will have two forms, one for the simple past tense and one for the past participle (also knowns as passive participle or perfect participle). The part participle represents the second of these two forms. For example, the verb eat has the simple past form of ate and also the past participle form of eaten. Another example, is write, wrote and written.

PRESENT_PARTICIPLE

public static final Form PRESENT_PARTICIPLE

The present participle is identical in form to the gerund and is normally used in the active voice. However, the gerund is meant to highlight a verb being used as a noun. The present participle remains as a verb. For example, Jim was sleeping.
