Morphology

influent = fluent (semi-transparent) = in + fluent

Structurally 'in-' + 'fluent' matches the meaning 'flowing in', but most learners know 'fluent' from language ability rather than 'flowing', so the connection may not be obvious.

Etymology

Influent comes from the Latin parts in- 'into' and fluere 'to flow', the same root you see in flow and fluid. So, influent means 'flowing into', used for water or another substance entering a larger body of water.
