Morphology
decaffeinate = caffeinate (semi-transparent) = de + caffein + ate
The prefix 'de-' straightforwardly adds the meaning of removal to the verb 'caffeinate'.
Etymology
Decaffeinate comes from de- meaning 'remove' and caffeine, a word made from 'coffee' for the chemical that can keep you awake. So to decaffeinate a drink is to take that chemical away and make the drink less likely to keep you awake.
