Morphology

depressurize = pressurize (transparent) = de + pressure + ize

The meaning is directly derivable as reversing or reducing the state expressed by 'pressurize'.

Etymology

Depressurize comes from the prefix de- meaning 'remove' or 'down' and the word pressure meaning 'force from air or gas'. So, to depressurize is to lower or take away the air or gas pressure in something, like letting air out of a balloon or a sealed chamber before you open it.
