A collective noun is a singular noun that designates a set. It does not name a single being or object, but a group perceived as a single reality. the crowd, the class, the collection and the team work this way. Without it, you would often need several words or a list of elements. With it, French gathers these elements under one name, as we have already seen for the Nouns.

The collective noun can designate people, animals, objects, or ideas. A band refers to a group of people, a herd of animals, a pile of objects, an ensemble of ideas or things related to each other. The noun keeps its singular form even when the elements of the group are numerous. We say therefore a troupe of actors, a swarm of bees, a series of books, a bouquet of flowers. The group changes, but the form of the collective noun remains the same.

Many collectives specify their content with a complement introduced by de or by à. This complement indicates the members of the group or the material gathered. We say an team of doctors, a herd of sheep, a handful of coins, a pile of luggage. With certain nouns, à serves to mark the composition or the destination, as in an assortment at low price or a themed collection. The collective noun remains singular, and the complement specifies what it contains.

The collective noun normally takes a determiner in the singular: a crowd, this group, my team. The adjective that qualifies it agrees with this collective noun, not with the members it designates: a small troop, a large family, a vast ensemble. When the group is presented as a single reality, all elements that depend directly on the noun follow its singular form. The determiner, the noun and the adjective are therefore built as for any singular noun, as in Nouns.

The verb can remain in the singular if the collective noun is viewed as a whole: The crowd advances, The class enters, A series begins. The verb shifts to the plural when the sense emphasizes the people or things that compose the group: The crowd applaudisson is not the normal form, but The crowd of supporters applaudissons draws attention to the supporters. In careful language, the singular is the most direct form with a collective noun taken globally. The plural appears when the sentence stresses the separate members rather than the whole.

Context decides whether the collective noun represents a unit or its elements. With The class listens, the class is seen as a unified group. With The class of students laughs in the hallway, attention shifts to the students themselves. Verbs, adjectives, and complements around the noun orient the reading. If the sentence speaks of organization, common movement, or collective action, the group remains global. If it describes individual behaviors, differences, or separate reactions, the members become more visible than the whole.

Some collective nouns almost always keep the same meaning: a band of, a troupe of, a swarm of, a crowd of. Others change value depending on the context. A mass can denote a tight group of people or things, but also a large quantity without a precise shape. A series can be an orderly set of objects, episodes, or actions. A people names a human group and can also designate an entire nation. When the word serves as a collective noun, it remains singular; when it designates a single abstract or material thing, it follows its own sense and is no longer read as a group.
