For purposes of verb agreement it is a third-person singular pronoun, though it sometimes appears with first- or second-person reference.
A pro-form is a function of a word or phrase that stands in for (expresses the same content as) another, where the meaning is recoverable from the context.
Similarly, in [6], others is a common noun, not a pronoun, but the others stands in for this list of names of the other people involved (e.g., Sho, Alana, and Ali).
This should be clear because, unlike pronouns, it readily takes a determiner (two) and an adjective phrase modifier (small), and because its plural form is the usual -s of common nouns.
Monarchs, people of higher classes, and particularly the late Queen Elizabeth II during her reign, are often depicted as using one as a first-person pronoun.
For example: However, some speakers find this usage overly formal and stilted, and do replace repeated occurrences of one with a personal pronoun, most commonly the generic he: Another reason for inserting a third-person pronoun in this way may sometimes be to underline that one is not intended to be understood as referring particularly to the listener or to the speaker.
Examples are also found, particularly in the spoken language, where a speaker switches mid-sentence from the use of one to the generic you (its informal equivalent, as described in the following section).
[16] A common and less formal alternative to the indefinite pronoun one is generic you, used to mean not the listener specifically, but people in general.
When excluding oneself, one can use the generic they: Other techniques that can be used to avoid the use of one, in contexts where it seems over-formal, include use of the passive voice, pluralizing the sentence (so as to talk about "people", for example), use of other indefinite pronouns such as someone or phrases like "a person" or "a man", and other forms of circumlocution.
