Summary: The English stem *plic* comes from a Latin root word meaning 'fold.' Some common English words that come from this word root include ap[*plic*]ation, multi[*plic*]ation, and re[*plic*]ate. Perhaps the easiest way to remember *plic* is through the word du[*plic*]ate, or to 'fold' twice, thus making two things.
