Singular or Plural Verb?

In British English, collective nouns can take either a singular or plural verb depending on meaning:

  • Singular (group acting as one unit): The team is winning.
  • Plural (group members acting individually): The team are wearing different coloured boots.

In American English, collective nouns almost always take a singular verb.

Note

Some collective nouns are fun and unusual. Learning them adds colour to your writing — teachers and examiners love them!

Real world: wildlife documentary narration

A pride of lions rested in the shade while a herd of elephants moved slowly toward the river. Overhead, a large flock of birds circled the sky, and in the water a shoal of fish darted past the rocks.

Real world: sports news report

The team is preparing for Sunday's final. The squad has been training hard all week. The crowd at the stadium was enormous — a band of musicians played before the match.

Tip Collective nouns appear in wildlife programmes ("a swarm of bees"), sports news ("the team is winning"), formal writing ("the committee has decided"), and everyday speech ("where are the keys?" — a bunch of keys). They are especially common in British English, where the group can take a plural verb when members act individually.

Practice Problems

Which collective noun fits? 'A __ of wolves howled at the moon.' (flock / pack / herd)

Show answer
'pack' — wolves travel in packs.

Is this correct? 'A swarm of bees are attacking the hive.' (British English)

Show answer
Both 'is' and 'are' are acceptable in British English. 'Are' treats the bees as individuals; 'is' treats them as one unit.

Name the collective noun for a group of fish.

Show answer
'school' or 'shoal' — both are correct for a group of fish.
