moronic

Etymology

It is formed from English moron + -ic.^[2][3][4][5] The noun was adopted in 1910 as a technical term in American psychology, from Ancient Greek μωρόν (mōrón), the neuter of μωρός (mōrós, “foolish, dull”),^{[2][3][6][7][8]} a word of uncertain origin.^[2][3][6] A connection with a Sanskrit word for foolish is given by Merriam-Webster and Partridge,^[9][10] but the OED says it is now generally rejected and Etymonline calls it doubtful.^[2][3] Latin mōrus (“foolish”) is a loan from the Greek adjective.^[3][7]

Earliest recorded meaning

Of or relating to a moron; characteristic of a moron: 1910, in the Pedagogical Seminary.^[2] Etymonline dates the adjective to 1911,^[3] and the Barnhart Concise Dictionary to 1926.^[4]

Semantic evolution

Henry H. Goddard proposed moron in 1910 for the highest grade of the "feeble-minded", and it was adopted by the American Association for the Study of the Feeble-minded for an adult with a mental age between 8 and 12.^[3][6] The noun was used as an insult in print by 1918, and later dropped from technical use;^[3] the OED records the sense "a stupid person" from 1922.^[2] The adjective followed the noun: the OED's single sense covers both the clinical "relating to a moron" and the general "foolish, idiotic",^[2] and the latter is now the usual meaning.^[9][1]
