Synonym discussion

Sense: noun/1

For sense 1, assembly is fairly formal and usually suggests an organized group brought together for one purpose, such as a protest, ceremony, or members' event. Gathering is broader and more everyday; it can be formal or casual. Meeting is narrower because it usually focuses on discussion or decisions. Congregation often has a religious feeling, or it can describe people gathered in a church. Crowd is the loosest word here and may describe many people in one place even if they are not organized. You might read about a peaceful assembly outside city hall, attend a family gathering on Sunday, join a staff meeting at work, or push through a crowd at the station.

Etymology

LatinFrenchEnglish

Assembly grew out of assemble and related French forms. At its core is a Latin idea meaning 'bring together'. The earliest uses were about people gathering for a shared purpose, and later the word widened to the industrial sense of fitting parts together.
