Sometimes, it’s fuzzy to figure out if a noun is singular or plural in French, particularly for collective nouns.
A collective noun is a word used in its singular form to express a set of items, 2 or more.
Examples of collective nouns are: the family, the police, the people…
The question is: ‘is this noun singular or plural in French?’ as it’s not consistent with English.
The police ARE (plural) here. ≠ La police EST (singular) là.
