🦷 molar = tooth for milling; Latin mola 'millstone' → grinder tooth
Spanish molar (tooth) comes from Latin mola, millstone, because back teeth grind food. The verb molar, 'to rule/rock', is slang and shares only the spelling: something that molas is great, like a tooth that does its grinding job well.
