Root Explanation
Sufficient → It is formed from "sufficere" (from Latin, meaning to meet or satisfy) which combines "sub-" (meaning under) and "facere" (meaning to make or do). The word "sufficient" means to be enough or adequate to meet a need or requirement.
Memory Tip
Think of something that is 'enough' to meet a need — 'sufficere' means to satisfy, so sufficient means it satisfies a requirement.
