The Collective Nouns English Actually Uses

About a dozen. Modern English uses flock, herd, school, swarm, pack, pride, pod, litter, colony, brood, hive and shoal without anyone noticing them. The famous ones, a murder of crows and a parliament of owls, come from a hunting manual printed in 1486, and they survive today as allusion rather than as description.

Where the strange ones came from

Nearly every list of animal group nouns on the internet is a partial reprint of one book, and the book was showing off.

The Book of Saint Albans was printed in 1486. It collects three treatises for gentlemen, on hawking, hunting and heraldry, with a fourth on angling added in the 1496 edition. The hunting section closes with an attribution to Juliana Berners, though scholars generally treat the work as compiled from earlier sources rather than written fresh.

Appended to it is a list of company terms for beasts and fowls, 164 items long. That list is the ancestor of every murder of crows you have ever seen quoted.

The giveaway is what else is on it. Alongside the animals sit a diligence of messengers, a melody of harpers, a blast of hunters, a subtlety of sergeants, a gaggle of women and a superfluity of nuns. Those are not observations about wildlife. They are jokes for an audience that would recognize them as jokes, mixed in with the hunting vocabulary because the whole exercise was a display of courtly cleverness.

Wikipedia’s account of terms of venery puts the consequence plainly: the book’s popularity “had the effect of perpetuating many of these terms as part of the Standard English lexicon even if they were originally meant to be humorous and have long ceased to have any practical application.” The same article notes that even in their own period the terms worked as kennings, “intended as a mark of erudition” rather than as everyday description.

Two later books kept the list alive. Gervase Markham reprinted it in 1595, and James Lipton’s An Exaltation of Larks put it in front of modern readers in 1968. Neither revived the usage. They revived the trivia.

The dozen that do real work

Strip out the ornamental terms and a small working set remains. These are the words a reader meets in ordinary prose and a speaker produces without thinking.

Term	What it groups	Where else it goes
flock	birds, sheep, goats	a flock of tourists, a flock of reporters
herd	cattle, horses, elephants, deer	herd mentality, herd immunity
school	fish, dolphins, whales	stays literal
shoal	fish, mostly British English	stays literal
swarm	bees, locusts, insects generally	a swarm of complaints, swarm intelligence
pack	wolves, dogs, hounds	a pack of lies, a pack of cards
pride	lions	stays literal
pod	whales, dolphins, seals	a pod of engineers, transport pods
litter	puppies, kittens, piglets	stays literal in this sense
colony	ants, bats, penguins, seals	a colony of expatriates, artists’ colony
brood	chicks, young birds	brood over a problem
hive	bees	a hive of activity

Twelve is a judgment call, not a measurement, and I would not fight anyone over the edges. Gaggle has a decent claim, for geese and for people. Murmuration has earned one. A birder will defend several more. The point is the order of magnitude: the working set is about this size, not 164.

Notice what the third column is doing. Most of the surviving terms have leaked out of the animal kingdom and into general use, which is a good sign that a word is alive rather than preserved.

The test that tells you which is which

If you are unsure whether a group term is usable, ask whether it travels.

A word that people genuinely use will show up somewhere it does not literally belong. Herd immunity is a public health term. A pack of lies has nothing to do with wolves. A hive of activity describes an office. Swarm has been borrowed by robotics. The metaphor is only available because the base word is common enough for the transfer to be understood instantly.

Now run the same test on the ornamental terms. Nobody writes a murder of complaints, an exaltation of results, or a shrewdness of colleagues except as a deliberate joke, and the joke depends on the reader recognizing the term from a list rather than from use. The metaphor never forms because the base word was never common enough to carry one.

The test works past animal groups too. It is a quick way to ask whether a word you have just met is part of the language or part of somebody’s curiosity collection, and the answer decides how much effort the word is worth.

The ones to recognize but not produce

These are worth knowing, because they turn up in headlines, crosswords, pub quizzes, nature documentaries and literary titles. They are not worth deploying.

• a murder of crows, attested since about 1475, and the most quoted of the whole set
• a parliament of owls, recorded from the fifteenth century for owls or rooks, and older as a joke than the list itself, since Chaucer had already written The Parliament of Fowls around 1382 and C. S. Lewis borrowed the pun for a chapter of The Silver Chair
• an exaltation of larks, familiar mainly as the title of Lipton’s book
• a shrewdness of apes, which sounds like a compliment about intelligence and was not one, since shrewd meant wicked or malicious around 1300 and only turned clever in the 1510s
• a bloat of hippos and a flamboyance of flamingos, both safari-brochure favourites
• an unkindness of ravens and a conspiracy of ravens, competing entries for the same bird

That split between knowing a word and using it is not a failure of learning. It is how most of a large vocabulary works: you understand far more words than you produce, and the gap is normal and permanent. We wrote about the difference between active and passive vocabulary and why trying to promote everything into active use wastes time.

There is a family resemblance here to another corner of English. Fossil words such as kith, fro and shrift survive only inside a single fixed phrase, and terms of venery survive only inside a single list. Both are words kept alive by their container, and we looked at what fossil words are and why they persist separately.

The one that came back

Murmuration is the interesting exception, and it shows what has to happen for one of these terms to return.

The word comes from the sound of the wings, a rustle like the murmur of a crowd. It sat in the same dusty list as the rest for centuries. Then cheap cameras and social video gave millions of people repeated exposure to the thing itself, tens of thousands of starlings turning in unison over a roost at dusk.

Now it is ordinary vocabulary in nature writing and in the news. RTÉ reported in March 2026 on murmuration tourism bringing visitors to Lough Ennell in County Westmeath, and the RSPB and the Natural History Museum both publish seasonal guides to spotting one. Nobody flags the word as archaic, because it is doing a job no other word does.

That is the whole mechanism. A group term survives when there is a recurring thing that needs naming and no simpler way to name it. A flock of starlings is accurate but says nothing about the shape in the sky. Everything else on the 1486 list failed that test, because a group of crows was always a perfectly good way to describe a group of crows.

Is the herd is or the herd are

The grammar question causes more real trouble than the vocabulary does, and it has a clean answer.

American English treats a collective noun as a single unit and uses singular agreement. The team is winning. The committee has decided. The family lives in Busan.

British English allows both, and the choice carries meaning. The committee has decided presents the group as one body speaking with one voice. The committee have been arguing all morning presents it as several people doing separate things. Sports coverage leans plural in British usage: England are playing well.

Three practical notes for learners:

• Singular agreement is the safer default in writing, especially for exams marked to an American standard.
• Keep the choice consistent inside one sentence. The team is playing well and they deserve it mixes the two and reads as an error even to speakers who accept both patterns.
• A number of takes a plural verb and the number of takes a singular one. A number of words are missing. The number of words is small. This pair is tested often and the rule does not bend.

Two group words that are not what they look like

School is two different words that arrived by different routes and collided in spelling.

The school you attend comes through Latin schola from Greek skholē, whose root sense is leisure, the free time in which a person could sit and argue. The school of fish is unrelated. It comes from Middle Dutch schole, a crowd or troop, recorded in English from the late fourteenth century and traced to a root meaning to cut or divide, so the underlying image is a division rather than a lesson.

Pod has the opposite history, in that nobody knows where the whale sense came from at all. It shows up in American English in 1827 meaning a herd of whales or seals, and the origin is simply unrecorded. That is worth remembering the next time a word list offers a confident story about it.

Both cases point at the same habit. A collective noun that looks like a word you already know is often a different word wearing the same spelling, and checking is cheaper than assuming. English is full of these collisions, and our words page gives the pronunciation and senses side by side when you want to see which sense is which.

What to do when you do not know the term

Say group.

This is the practical advice that word lists never give, and it is what native speakers do constantly. A group of crows, a group of dolphins, a lot of bees. None of it is wrong, none of it is even marked, and no reader stops to notice. Fluent speech is full of general words used where a specific one exists, because retrieving the specific one is slower than the conversation.

The failure mode is the opposite: a learner who has memorized sixty terms of venery, stalls mid-sentence hunting for the right one, and produces something that sounds either archaic or accidentally comic. That is a worse outcome than the plain word would have been.

Use the working dozen, because those are genuinely more precise and cost nothing to retrieve. Leave the rest in recognition memory where they belong.

How to learn the ones that matter

The dozen useful terms are not hard words. What makes them stick is the collocation, meaning which animal each one attaches to, plus the metaphorical extensions that show the word is alive.

That is a job for example sentences rather than definitions. A gloss like “flock: a group of birds” records almost nothing. A sentence with a flock of tourists in it records the reach of the word.

Vocaby is built for that. It carries 29,000-plus English words with IPA, audio pronunciation, plain-English definitions and real example sentences, and it schedules reviews with FSRS so the words that are slipping come back before you lose them. Hearing pod and brood spoken also settles the vowel, which is where these short words tend to go wrong for Korean speakers.

The 1486 list was a game for people who already spoke the language fluently. Learn the twelve that survived it, recognize the rest when they appear, and spend the saved effort on words you will actually say.
