Root Explanation

Monotonic → It is formed from "mono-" (meaning one or single) and "tonic" (from Greek "tonikos", meaning relating to tension or tone). The word "monotonic" refers to a single tone or a constant tone without variation.

Memory Tip

Think of 'mono-' meaning 'one' and 'tonic' relating to 'tone' — so a monotonic sound is one that stays at a single tone without changing.
