Root Explanation

Monotonicity → It is formed from "mono-" (from Greek "monos", meaning single or alone) and "tonic" (from Greek "tonikos", meaning relating to tension or tone) combined with the suffix "-ity" (meaning the state or condition of). The word refers to the state of being single-toned or having a consistent tone throughout.

Memory Tip

Think of 'mono-' meaning single and 'tonic' relating to tone — this helps you remember that monotonicity refers to a consistent or single tone throughout.
