Morphology

liberate = liberty (semi-transparent) = liber + ate

The technical sense 'to release (a gas, energy, etc.)' extends the basic idea of 'free/release' but is more specialized, so learners may not immediately map it to everyday 'set free'.

Etymology

Liberate comes from the Latin root liber, meaning 'free', and in science the idea stays the same: a reaction 'frees' a gas or energy, so the reaction liberates those substances.
