Morphology

evaporation = evaporate (transparent) = evaporate + ation

The noun is a regular nominalization of the verb 'evaporate' using the productive suffix '-ation', so the process meaning is directly derived from the verb.

Etymology

Evaporation comes from Latin parts meaning 'out' and 'steam': ex- 'out' and vapor 'steam'. So evaporation is when a liquid turns into 'steam' and goes 'out' into the air, which helps you remember why puddles disappear on a hot day.
