Morphology

tributary = tribute (semi-transparent) = tribute + ary

Formed from 'tribute' + '-ary', but the hydrological meaning ('a stream that gives water') is a metaphorical extension rather than a literal transfer, so learners may not predict it directly.

Etymology

Tributary comes from the same root as tribute, from a Latin word meaning 'to give'. Imagine a small stream 'giving' its water to a bigger river — that is why a tributary is described as flowing into a larger waterway.
