Morphology

monophthong = phthong (semi-transparent) = mono + phthong

The word is built with the familiar Greek combining form mono- plus a technical element meaning 'sound', but the second element is not a familiar standalone word for most learners.

Etymology

Monophthong breaks into mono- 'one' and phthong 'sound', like in phone. It means a vowel that stays as a single, unchanging sound, so a monophthong is a vowel you say with one steady sound the whole time.
