Monophonically → It is formed from "mono-" (from Greek "monos", meaning single or alone) and "phonic" (from Greek "phonē", meaning sound) and the suffix "-ly" (meaning in a manner). The word "monophonically" means in a manner that involves a single sound or voice.
Think of 'mono-' meaning 'single' and 'phonic' relating to 'sound' — this helps you remember that 'monophonically' refers to something that involves just one sound.
