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:

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

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

Examples:

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

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

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:

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

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

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