Root Explanation

Reciprocator → It is formed from "re-" (meaning again) and "cipere" (meaning to take) combined with the suffix "-ator" (meaning one who). The word describes one who takes or receives something again, often in a mutual exchange.

Memory Tip

Think of someone who 'takes again' ('re-') in a mutual exchange — that's what a reciprocator does.
