Root Explanation

Costlessly → It is formed from "cost" (from Old French *coste*, meaning expense or price) and "-less" (meaning without). The word "costlessly" means without cost or expense.

Memory Tip

Think of 'cost' as the price you pay and '-less' meaning without — so costlessly means without any price.
