Surface Forms

Morphology

depressurization = depressurize (transparent) = de + pressure + ize + ation

Standard noun formation from the verb 'depressurize' denoting the process of that action.

Etymology

Depressurization comes from de- meaning 'down' or 'remove' and pressure meaning 'force' or 'air pushing'. A helpful image is letting air out of a balloon or a sealed cabin, and that is why depressurization means reducing or losing air pressure in a closed space.
