Morphology

deflate = inflate (transparent) = de + flate

For the literal physical sense, 'deflate' is readily understood as the reversal of 'inflate', meaning to let air or gas out.

Etymology

Deflate comes from the prefix de- meaning 'remove' and the same root as inflate meaning 'to blow air in', so to deflate something is to 'take the air out' and make it flat.
