Root Explanation

Operatorless → It is formed from "operator" (from Latin "operari", meaning to work) and "-less" (meaning without). The word "operatorless" means without an operator or someone who works or operates something.

Memory Tip

Think of being 'without' ('-less') someone who 'works' ('operari') — that's why operatorless means lacking an operator.
