Plural of “person”

The plural of person is people.

Why

"Person" is Latin in origin ("persona," originally a theatrical mask, later a role or individual), but its everyday plural, "people," isn't a Latin plural at all — it's a completely different word, from Old French "peupel" (ultimately Latin "populus," meaning "the populace"), making "person/people" a case of suppletion, where a plural is supplied by an unrelated word rather than by inflecting the singular.

A genuinely regular plural, "persons," does exist and survives in narrow legal and bureaucratic registers ("missing persons," "no more than four persons per vehicle," "persons of interest"), precisely the contexts that need precise, individually-countable language — everywhere else, "people" dominates as the ordinary plural for any general group of humans. Linguists often reach for "person/people" as the textbook illustration of suppletion when first teaching the concept, pairing it with "go/went" from the verb system, since in both cases a wholly different word steps in where a regular form would otherwise be expected. "People" itself arrived in English by way of Anglo-Norman French in the centuries after the Norman Conquest, stacking a French-derived plural onto a Latin-rooted singular — a layering typical of how English vocabulary absorbed multiple source languages during that era.

Usage note

"People" itself is also a distinct, older noun meaning "a nation or ethnic group" ("the peoples of Southeast Asia"), and in that specific sense it pluralizes as "peoples" — a genuinely different countable noun from the everyday plural of "person," not a further irregularity of it.

"Peoples," the plural of "people" in its nation/ethnic-group sense, is easy to mistake for a simple error since "people" already looks plural, but it's a legitimate and necessary form whenever a writer needs to refer to more than one distinct ethnic or national group in the same sentence, a genuinely separate grammatical need from simply describing a number of individual humans. Legal and bureaucratic English has preserved "persons" far more robustly than general usage has, partly because precise, individually-countable language matters more in contracts, statutes, and official forms, where ambiguity about exactly how many individuals are covered by a rule can have real legal consequences.

Common real mistakes

Writing "persons" in ordinary conversational contexts ("three persons were waiting") sounds stiff and overly formal to most readers; "people" is the natural, unmarked choice outside legal, statistical, or highly formal bureaucratic writing, and reaching for "persons" there is a register mismatch rather than a grammatical mistake. A further wrinkle: some regional and informal varieties of English use "peoples" loosely to mean simply "a lot of people" rather than distinct ethnic groups, a nonstandard usage most style guides discourage in formal writing.

The wider pattern

Suppletive plurals like "person/people" are rare in English, but the same mechanism, an unrelated word standing in for the expected plural, shows up in a handful of other core vocabulary pairs cross-linguistically, though "person/people" is by far the most frequent example a native English speaker encounters daily.
