Morphology

sedimentary = sediment (transparent) = sediment + ary

The adjective is a regular derivation from the noun 'sediment' with the productive suffix '-ary', so its meaning 'relating to or formed from sediment' is directly inferable.

Etymology

Sedimentary comes from the Latin root sedere, which means 'to sit' or 'to settle', and is the same root as sediment, the bits of sand or mud that 'sit' at the bottom of water. So sedimentary rocks are made from layers of material that have settled and then turned into rock.
