Morphology
deflation = deflate (opaque) = de + flate + ion
The geological sense ('removal of loose material by wind') is a specialist technical meaning that cannot be derived from the everyday sense 'let air out'.
Etymology
Deflation comes from the Latin parts de- ('down' or 'away') and flate (from flare, 'to blow'), the same root as inflate. In geology, deflation is nearly literal — wind 'blows away' loose soil and sand, leaving the land lower or bare.
