Root Explanation
Quintuple → It is formed from "quintus" (meaning fifth) and "-ple" (from Latin "plicare", meaning to fold). The word "quintuple" means to fold or multiply something five times.
Memory Tip
Think of 'fifth' ('quintus') and 'folding' ('-ple') something five times — that's why quintuple means to make five times as much.
