Etymology

Noun

from Latin molaris "a grinding tooth," from mola "millstone" — related to mill entry 1

Word Origin
Food is crushed in the mouth by the grinding of teeth, especially the molars. In much the same manner, grain may be ground into flour between two rough circular millstones. The Latin word for millstone is mola, and it seemed fitting to the English in the late Middle Ages that a tooth which acted like a millstone be called a molar.
