Adjective + noun

Simplified etymology

Molar entered English in the Middle Ages and derives from Latin molere, “to grind.” It was so named because molars are the teeth used for grinding food.

Etymology

The dental word comes through Middle English and Latin molaris, "millstone tooth," from mola, "millstone," likening the tooth to a grinding stone. The chemistry adjective was formed independently from mole, the unit of amount of substance, + -ar.
