Plural of “man”
The plural of man is men.
Why
"Man" and "men" descend from Old English "mann" and "menn," shaped by the same i-mutation sound process behind "mouse/mice" and "foot/feet": an old plural ending fronted the vowel before disappearing, leaving the vowel change itself as the plural marker that survives today.
Compounds built on "man" generally inherit the same irregular plural — "policeman/policemen," "postman/postmen," "gentleman/gentlemen" — but many of these occupational compounds have shifted in recent decades toward gender-neutral alternatives ("police officer," "mail carrier"), a change driven by usage norms rather than by any grammatical instability in the plural pattern itself, which remains fully regular for whichever compounds still use "-man." The word's use as a generic term for humanity as a whole ("the history of man") has become increasingly controversial and less common in contemporary writing, with many style guides now recommending "humanity" or "humankind" instead, a shift driven by concerns about the generic masculine excluding half the population by default rather than by any grammatical instability in the countable noun's own plural. The distinction between this older generic usage and the ordinary countable plural "men" (referring specifically to adult males) is worth keeping separate, since the two uses raise entirely different concerns despite sharing the same singular word.
Usage note
Not every "-man" compound pluralizes this way: "human," despite looking like it contains "man," pluralizes as the fully regular "humans," not "humen," because it's historically unrelated in formation — "human" comes from Latin "humanus" and only resembles "man" by coincidence of spelling, not by derivation.
"Mankind," the older collective term for humanity, is grammatically singular through and through, with no plural form at all — quite unlike the countable noun "man" it's derived from — and many style guides today steer formal writing toward "humanity" or "humankind" instead, a shift connected to, though distinct from, the wider retreat from generic masculine "-man" compounds elsewhere in the language. Sports and military terminology still hang onto a handful of "-man" compounds that pluralize with "-men" regardless of who actually fills the role today ("linemen" in football, "crewmen" in various naval contexts), a case where entrenched compound grammar has simply lagged behind the changing demographics of the people doing those jobs.
Common real mistakes
The reverse of the "human/humans" mistake shows up surprisingly often — learners who've internalized "man/men," "woman/women," and "policeman/policemen" sometimes produce "humen" by false analogy, not realizing "human" was never actually built from "man" the way those other pairs were. It's also worth keeping the countable plural "men" separate from the uncountable collective "mankind": treating the two as interchangeable ("mankind are progressing") creates a subject-verb agreement slip that's a distinct issue from, if related to, the larger conversation around generic masculine terms.
The wider pattern
"Man/men" is part of the same Old English i-mutation family as "woman/women," "foot/feet," "tooth/teeth," "goose/geese," and "mouse/mice" — six of English's most frequent irregular plurals all trace to the identical vanished sound process.
