stupefy

Etymology

It is inherited from Middle English stupefien, also stupifien,^[2][3] borrowed from Middle French stupefier,^[4][3][5][6] although the French verb is first recorded slightly later, in the late 15th century;^[4] Etymonline and the Middle English Dictionary take it directly from Latin.^[7][2] The source is Latin stupefaciō (“to stun, daze, benumb”),^[4][7][8] formed from stupeō (“to be stunned, struck senseless”) and faciō (“to make, do”),^[4][7][8][9] the latter from Proto-Indo-European *dʰeh₁- (“to set, put”).^[7] Merriam-Webster Unabridged notes that the French form was shaped by the French verbs in -fier (see -fy).^[5] The OED compares Old Occitan stupefar.^[4][2] The Latin verb is the source of stupefaction, and its base of stupid and stupor.^[3][10]

Earliest recorded meaning

In medicine, to numb a part of the body or deaden a pain: before 1425, in a translation of Chauliac's Grande Chirurgie, of cold water held in the mouth that stupifieþ an ache.^[2][3][7][4]

Semantic evolution

The medical sense was extended to dulling the senses or the mind in general.^[4][7] The sense "to overwhelm with wonder, astound" is recorded from 1577,^[4] in the 1590s according to Etymonline, and in 1596, in Spenser's Faerie Queene, according to Barnhart.^[7][3] From 1601 the verb meant to make a person mentally or emotionally dull,^[4] and Bacon used it of depriving a substance of its fluidity.^[4] The spelling stupify was common until the second half of the 19th century,^[4][7] and Johnson (1755) remarked that the word "should..be spelled stupefy; but the authorities are against it".^[4]
