Root Explanation
Resultless → It is formed from "result" (from Latin "resultare", meaning to spring back or rebound) and "-less" (meaning without). The word "resultless" means without a result or outcome.
Memory Tip
Think of 'result' meaning an outcome, and '-less' meaning without — so 'resultless' means having no outcome.
