Morphology

tributary = tributary (opaque) = tribute + ary

The noun is a zero-derived use of the adjective 'tributary', but the river sense is a historical metaphor that is not readily recoverable from the base meaning.

Etymology

Tributary takes its name from the root tribute, which means 'to give'. A tributary is a smaller river that 'gives' its water to a larger one, so the name shows its role as a feeder to the main river.
