Plural of “moose”

The plural of moose is moose.

Why

"Moose" has no plural of its own because English never had one to give it — the word was borrowed directly from Eastern Abenaki "mos" (via other Algonquian languages) in the early 1600s by colonists who needed a name for an animal Old English simply had no word for. Loanwords adopted whole from another language family don't automatically inherit English's native plural machinery, and "moose" arrived with no plural marker attached in its source language, so English speakers simply never bothered to invent one.

This sets "moose" apart from English's other famous zero-plural animal names. "Sheep" and "deer" are native Old English words that lost a distinct plural ending over a thousand years of sound change; "moose" never had one to lose, because it entered the language fully formed as a loanword within the last four centuries. The unchanged plural likely stuck, and spread to other large game animals named later, partly by analogy with those older zero-plural hunting terms already familiar to English speakers.

Usage note

"Moose" is always "moose," whether you mean one animal or fifty; there is no separate singular-versus-plural spelling to worry about, and the verb agreement simply follows whatever number the sentence establishes elsewhere ("a moose was" versus "three moose were").

You'll sometimes see "meese" used as a joke, modeled humorously on "goose/geese," but it has never been standard English in any register — it survives only as a deliberate pun, never as a genuine competing plural the way "cactuses" competes with "cacti." Wildlife agencies' own regulatory language leans on the zero plural constantly, setting annual "moose hunting quotas" and "moose population targets" without ever needing a marked plural form, which is part of why the unchanged spelling feels so unremarkable to anyone who reads hunting regulations or wildlife reports regularly.

Common real mistakes

The main slip is adding an -s out of habit ("mooses"), which is understandable since almost every other English noun pluralizes that way, but it isn't accepted in standard usage for this particular animal. A second, subtler error is assuming every large mammal name behaves the same way — "elk" and "bison" also resist a plain -s plural, but "bear" and "wolf" pluralize normally, so the zero-plural pattern has to be learned animal by animal rather than applied as a blanket rule.

The wider pattern

"Moose" belongs to a small cluster of game-animal names that stay identical in the singular and plural — "deer," "sheep," "elk," "bison," and "swine" among them — but unlike the native English members of that group, "moose" got there by being borrowed whole from Algonquian rather than by losing an Old English plural ending over centuries of sound change. "Moose" is also notable for pairing with gender terminology borrowed from cattle rather than dedicated vocabulary of its own: a male is a "bull moose," a female a "cow moose," and a young animal a "moose calf" — unlike "deer," which developed its own distinct terms, "buck," "doe," and "fawn." Whichever modifier precedes the noun, it never takes a separate plural of its own: "three bull moose" grazing together, never "three bulls moose."
