Morphology

decomposition = decompose (semi-transparent) = de + compos + ition

The noun is transparently formed from the verb 'decompose' plus the noun-forming suffix '-ition', but the specialized chemical sense may not be fully predictable.

Etymology

The word decomposition comes from the prefix de- meaning 'down' or 'away' and the root compose meaning 'put together', so it means taking apart what was once put together. In chemistry this describes how a compound is broken into simpler substances.
