Morphology

chlorophyll = chloro + phyll (semi-transparent) = chloro + phyll

Composed of Greek combining forms that together indicate 'green' + 'leaf' for a pigment in plants; the elements are familiar in scientific contexts but are not independent everyday English words for most learners.

Etymology

Chlorophyll comes from Greek parts chloros 'green' and phyllon 'leaf', so it literally means 'green leaf'. That's why chlorophyll is the green substance in leaves that helps plants capture sunlight to make food.
