Number: number

In English, Number is a feature of nouns and other parts of speech that mark agreement with nouns, i.e. personal pronouns, verbs, and some determiners.

Sing: singular

A singular noun denotes one person, animal or thing. Every noun with the PTB tag NN or NNP is marked with this feature.

Examples:

• an apple, a train

Pronouns that refer to a single person, an animal or a thing are also marked with this feature.

• I, me, my, myself, he, his, him, himself, she, her, hers, herself, it, its, itself

We also mark all verbs with the PTB tag VBZ with this feature.

Examples:

• she does
• he walks

Further, we mark inflections of be that can only have a singular noun or pronoun in subject position with this feature.

• am, is, was

Demonstrative determiners of singular nouns and demonstrative pronouns that refer to singular nouns are also marked with this feature.

• this, that

Plur: plural

A plural noun denotes several persons, animals or things. Every noun with the PTB tag NNS or NNPS is marked with this feature.

Examples:

• several apples, two trains

Pronouns that refer to a single person, an animal or a thing are also marked with this feature.

• we, us, our, ours, ourselves, yourselves, they, them, their, theirs, themselves

Demonstrative determiners of plural nouns and demonstrative pronouns that refer to plural nouns are also marked with this feature.

• these, those

We currently don’t mark plurale tantum or collective/mass nouns.
