The noun confluence means the situation in which two things joined and became one larger thing.

Synonyms are assemblage, assembly, concourse, or junction.

The word origins from Late Latin (early 15th century) confluentia meaning “a flowing together, especially of two or more streams”, from Latin confluentem. It is the present participle of confluere meaning “to flow together”. It comes from assimilated form of com meaning “with, together” plus fluere meaning “to flow”.
