Morphology

deficient = deficit (transparent) = deficit + ent

The adjective is clearly related to the noun 'deficit' and denotes having a shortage or lack, a relation that is directly inferable for learners.

Etymology

Deficient comes from the Latin word deficere, made of de- 'away' and facere 'to do', and it once meant 'to fail' or 'to be missing'. It is like the word deficit, which means 'a shortage', so something deficient does not have enough of what it needs.
