For instance, English "something" can be used only in affirmative contexts while "anything" is used otherwise.
Thus, all is an indefinite determiner in "all good boys deserve favour" but a pronoun in "all are happy".
Most indefinite pronouns correspond to discretely singular or plural usage.
However, some of them can entail singularity in one context and plurality in another.
Pronouns that commonly connote indefiniteness are indicated below, with examples as singular, plural, or singular/plural usage.
These are made as for nouns, by adding 's or just an apostrophe following a plural -s (see English possessive).
