Morphology

flavonoid = flavone (semi-transparent) = flavone + oid

Formed by the regular suffixation 'flavone' + '-oid' meaning 'resembling/related to flavone', but both elements are specialised chemical terms unlikely to be known by general learners.

Etymology

Flavonoid comes from the Latin word flavus, meaning 'yellow', plus the ending -oid, meaning 'like'. So flavonoids are 'yellow-like' plant substances that often give color to fruits and flowers and can help protect health.
