Real-World Examples

See how these words work in genuine contexts — from business emails to academic papers.

📏 Basic:

The dog runs in the park. The dogs run in the park.

Singular subject = singular verb (-s). Plural subject = plural verb (no -s).

⚠️ Tricky:

The list of items is on the table.

'List' is the subject (singular), not 'items' — don't be fooled by the prepositional phrase

⚠️ Compound:

Tom and Jerry are friends. Neither Tom nor Jerry is available.

'And' = plural verb. 'Neither...nor' = verb matches the nearest subject.

⚠️ Collective:

The team is winning. (American) The team are winning. (British)

Collective nouns: American English treats as singular, British as plural

❌ Common Error:

There is too many problems with this plan.

Wrong: 'problems' is plural. Should be: 'There are too many problems.'

💡 Rule:

Find the TRUE subject (ignore prepositional phrases), then match the verb.

Cross out 'of...' phrases to find the real subject

Why Do People Confuse Them?

The #1 cause of agreement errors is prepositional phrases between subject and verb that contain a noun of different number: 'The box [of chocolates] is...' The brain sees 'chocolates' (plural) right before the verb and reaches for 'are.' Mentally crossing out prepositional phrases reveals the true subject.
