Root Explanation

Deficient → It is formed from "de-" (meaning down or away) and "facere" (meaning to make or do). The word "deficient" describes something that is lacking or not fully made, indicating a state of being less than what is necessary or required.

Memory Tip

Think of something that is 'down' or 'away' from being fully 'made' — that's why deficient means lacking or not enough.
