Plural of “boy”

The plural of boy is boys.

Why

"Boy" has a genuinely disputed origin — some scholars trace it to an Old French word for a fettered servant or a person in chains, while others suggest a purely imitative or affectionate coinage similar to "baby." Whatever its exact source, it entered Middle English as a word for a young male, and because a vowel, o, comes immediately before the final y, it takes only a plain -s rather than the -ies ending required after a consonant. A third theory links it to a Germanic root meaning simply "young person," without any original connotation of servitude at all, and modern etymological dictionaries generally present all three explanations without fully endorsing one over the others.

That uncertainty over the word's origin is unusual for such a common, everyday noun; most frequently used English words have at least a reasonably well-documented history, but "boy" remains one of the more genuinely debated etymologies among linguists, despite the word itself being entirely unremarkable in modern use.

Usage note

"Boys" is standard across every context, from casual reference to children to its broader, more informal use for grown men in certain dialects and idioms ("the boys down at the shop").

The proposed Old French link to a word for a fettered servant remains genuinely speculative among etymologists, and some dictionaries instead simply mark the word's origin as "unknown" or "obscure" rather than committing to any single theory, an honest acknowledgment that not every common English word has a fully solved history. "Boys" also appears constantly in fixed idiomatic and cultural phrases, from "boys will be boys" to "the boys in blue" (referring to police), each treating the plural as shorthand for a recognizable social group rather than literally counting individual boys. The word also appears in the fixed exclamation "oh boy," an idiom expressing surprise or dismay that has nothing to do with age or gender and never pluralizes since it functions as an interjection rather than a noun.

Common real mistakes

The plural itself is about as safe as English spelling gets, requiring no letter change at all; the only notable confusion involves the word's informal, sometimes dated use to describe grown men, a question of tone rather than of spelling. Writers should also be mindful that historically "boy" was sometimes used in demeaning, racially charged ways to address grown men, a usage now widely recognized as offensive and avoided entirely in respectful modern writing.

The wider pattern

"Boy" follows the same vowel-plus-y pattern as "key" and "toy," and its uncertain etymology is a useful contrast to more thoroughly documented words in this family like "lady," whose Old English compound origin is well understood.
