What Animals Form a Troop?
From the treetops to the tall grass, two very different mammals share one very old word.
Which Animals Form a Troop?
Two animals on Gaggle of Nouns are described with the collective noun troop: chimpanzees, whose extended communities of dozens of individuals split apart and reunite throughout the day, and mongooses, whose tight family groups forage and stand sentry together. Both are highly social mammals, which is the common thread — “troop” tends to land on animals whose groups look organized, cooperative, and almost military in their coordination.
Where Does “Troop” Come From?
“Troop” is first attested in English in the 1540s, borrowed from French troupe, itself from Old French trope/trupe (“band of people, company, crowd”), first recorded in the 13th century. Its ultimate origin further back is genuinely uncertain — etymologists have proposed a Frankish root related to Old English ðorp and Old Norse thorp (“village”), and separately a Latin troppus (“flock”), but neither is confirmed. What is clear is the sense shift: “troop” meant military forces first, broadened to “any assemblage of people” by the 1580s, and was applied to animal groups from there.
Troop vs. a Scout Troop (and Troupe)
Unlike a lot of collective nouns that borrow an unrelated everyday word, “troop” isn’t secretly a different word in disguise — a Boy Scout troop, a troop of soldiers, and a troop of chimpanzees are all literally the same word, in the same sense of “an organized band,” just applied to different kinds of groups. The one true look-alike worth knowing is troupe (a troupe of dancers or performers), spelled with a final e — a closely related word from the same French root that split off to specialize in the performing arts. Gaggle of Nouns also has a page for “Troup” (no final e, no second o), currently applied here to shrimp; that spelling doesn’t appear as its own entry in major dictionaries, so it looks more like a variant of “troop” than a genuinely separate word — see that page for the full rundown.
Animal-by-Animal Breakdown
Chimpanzees: Most commonly called a troop in general and popular usage, though field primatologists studying wild chimps often use the more technical term “community” for the same fission-fusion social group. On this page, “troop” is chimpanzees’ primary, go-to term, not an afterthought.
Mongoose: Most commonly called a mob, with pack and gang also in wide use. “Troop” is a genuinely documented alternate for mongooses — particularly associated with cooperative species like the banded mongoose — but it’s a secondary term here, not the top pick.

Frequently Asked Questions
What is the collective noun for a group of chimpanzees?
A group of chimpanzees is most commonly called a troop, though scientists studying wild chimps often use the term community for the same social group.
What is the collective noun for a group of mongooses?
A group of mongooses is most commonly called a mob, with pack and gang also widely used. Troop is a real but secondary alternate, especially for cooperative species like the banded mongoose.
Is “troop” the same word as a Boy Scout troop?
Yes. A Boy Scout troop, a troop of soldiers, and a troop of chimpanzees all use the same word in the same sense of an organized band, just applied to different kinds of groups.
Is “troop” related to “troupe”?
Yes. Both descend from the same French word, troupe, meaning a band of people. Troupe kept the French spelling and narrowed to mean performers, while troop became the general English form.
Is the “Troup” page on this site a typo of “Troop”?
It looks that way. Gaggle of Nouns also has a page for “Troup,” currently applied to shrimp, but that spelling doesn’t appear as its own headword in major dictionaries, which suggests it’s a variant of “troop” rather than an independently attested word.
