Morphology

anorthitic = anorthite (transparent) = anorthite + ic

Standard adjective formation from the noun 'anorthite' using the productive suffix '-ic', yielding 'relating to anorthite'.

Etymology

The word anorthitic comes from the mineral name anorthite, which itself comes from the Greek parts an- 'not' and orthos 'straight', the same root you see in orthodox. The name pointed to crystals that were 'not straight', and today anorthitic simply means 'relating to anorthite', a kind of feldspar that has a lot of calcium.
