Etymology

Origin of confluence

First recorded in 1375–1425; late Middle English, from Middle French, from Late Latin confluentia, from Latin confluent-, stem of confluēns “flowing together” ( confluent ) + -ia -ia

Explanation

Confluence means a flowing together. In a literal sense, it's about rivers. But it's more often used to talk about the coming together of factors or ideas, or of cultures in a diverse city. Con- means "with," and -fluence sounds like "flow." When things come together like rivers do, flowing from entirely different places, you call that a confluence. If the senior class needs to raise money for a class trip, and the drama club is looking for someone to do concessions during intermission at the school play, that's a confluence of factors.
