Conversation

I've been feeling a bit tired lately, I think I might have a deficiency in vitamins.

That could be it! Have you been eating enough fruits and vegetables?

Not really, I've been busy and skipping meals.

Root Explanation

Deficiency → It is formed from "de-" (meaning down or away) and "facere" (meaning to make or do), combined with the suffix "-cy" (indicating a state or condition). The word "deficiency" refers to the state of being down or lacking in something that is necessary or required.

Memory Tip

Think of being 'down' ('de-') in what you 'make' or 'do' ('facere') — that's why deficiency means lacking something essential.
