Morphology

chlorite = chlorine (semi-transparent) = chlor + ite

The combining form 'chlor-' means 'green' and '-ite' is a mineral-forming suffix, but 'chlor-' is not a standalone English word and '-ite' is specialized vocabulary, so the relation is only partly transparent to average learners.

Etymology

Chlorite comes from the Greek root chlor- meaning 'green' and the mineral ending -ite, the same chlor- you see in chlorophyll, which makes plants green. So chlorite is simply a 'green' mineral, which is why it often appears as flat green or dark crystals in rocks.
