Forms

molārius (feminine molāria, neuter molārium); first/second-declension adjective[1]

Etymology

It is formed from Latin mola + -ārius, from mola (“millstone, mill”).[2][1][3] De Vaan traces mola to Proto-Indo-European *molh₂-h₂- (“mill(stone)”), from the root *melh₂- (“to crush, grind”),[3] which also gave the verb molō “to grind”.[3]

Earliest recorded meaning

Cato has it first, in the phrase asinus molarius, the donkey that turns a mill, listed among the equipment of an olive yard and a vineyard.[4][5][3][6]

Semantic evolution

In Classical Latin it remained an adjective meaning “of a mill, for grinding”: Varro repeats Cato's mill donkey,[5][4] and Vitruvius uses it of a mill.[7]

In medieval Latin it became a noun for a miller,[8][9][6] which also served as a surname (Miller, Meunier) in British records.[9] Du Cange records a molarius who quarries and cuts millstones, in a charter of 1299,[10] and in Hungary lapis molarius is a millstone.[11] Wiktionary lists Romanian morar (“miller”) and Aromanian murar as possible descendants.[1]
