Etymology

Origin of mineral

First recorded in 1375–1425; late Middle English, from Middle French, Old French mineral, from Medieval Latin minerāle (noun), minerālis (adjective), from miner(a) “mine, ore,” (from Vulgar Latin mināria (unrecorded); equivalent to mine ² + -ary ) + -āle, -ālis -al ¹

Explanation

A mineral is a nonliving natural substance of a definite chemical composition. A mineral like manganese may help keep you healthy; a mineral like a diamond may help keep you sparkly. At one time mineral referred to valuable substances obtained in mines. Although that still can be the case, today the word has several senses (both noun and adjective) and may be found almost anywhere — in the ground, in the air, or on the periodic table. And if you remember mineral when you remember animal and vegetable, you’ve got a better chance of winning Twenty Questions.
