Morphology

decaf = decaffeinated (semi-transparent) = de + caf

The noun is a common clipping of 'decaffeinated', but learners may not fully recover the source form from the shortened shape alone.

Etymology

Decaf is short for de- 'remove' plus the caf part from caffeine, which is the part of coffee that keeps you awake. So decaf means coffee 'without' caffeine or with very little of it.
