Final answer:
Another term for a large gathering of people is 'assemblage', implying a group with organization or common intent, different from a crowd which lacks specific interaction or shared identity.
Step-by-step explanation:
The term for a large gathering of people is assemblage. The word refers to a group of individuals who convene for a common purpose or spontaneously. Different from a mere collection of individuals in proximity like a crowd or an aggregate, an assemblage implies more organization or common intent.
A gathering can also range from a small number of people, such as a group project in school, to a larger collective akin to a rally, which is usually a one-time event. Regardless of size, an assemblage implies a certain level of interaction or shared identity among the participants, distinguishing it from a crowd, which is a fairly large number of people in close proximity without a specified interaction or identity.
