Morphology

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

This is a standard noun formation from the verb 'decompose' meaning the process or result of decomposing.

Etymology

The word decomposition comes from de- 'down' or 'away' and compose 'put together', so it means breaking something apart into smaller pieces. A helpful image is a compost heap, where dead plants are broken down by tiny organisms into rich soil, which is exactly what happens to organic matter.
