Plural of confluence; multiple points where rivers or streams flow together, or where different things come together.
From Latin confluentia, from confluens (flowing together), combining con- (together) + fluere (to flow). Standard geographical term with classical roots.
Major confluences shape human civilization—cities like Pittsburgh (where three rivers meet) and Cairo (at the Nile Delta) thrived because confluences provided transportation, food, and water power.
