Replication → It is formed from "re-" (meaning again) and "plicare" (meaning to fold). The word "replication" means the act of folding or repeating something again.
Think of doing something 'again' ('re-') and 'folding' ('plicare') it — that's why replication means to repeat or reproduce something.
