powerful

Etymology

It is formed from English power + -ful,^{[2][3][4][5][6][7]} Middle English pouerful and powarfull.^[2][5][8] Power is from Anglo-Norman pouair, from Old French povoir (“to be able”), which goes back to Latin potis (“powerful”), from Proto-Indo-European *poti- (“powerful”).^[2]

Earliest recorded meaning

Mighty, having power over others: the first quotation in the OED and the Middle English Dictionary is from the Wars of Alexander, in a manuscript of about 1450 and perhaps composed before 1400: My pure powarfull gods I prestly pauoure.^[3][5] Etymonline dates the word to about 1400,^[2] and Dictionary.com to 1350–1400.^[8]

Semantic evolution

The word begins with power over others and is widened in the later 16th century to any great force or ability, from about 1567; to things that exert force or have a strong effect, from 1583; and to speech or art that convinces and moves, from 1588.^[3][4] Johnson (1755) separates "invested with command or authority", "forcible; mighty" and "efficacious", the last of which the 1773 edition illustrates with a powerful medicine.^[7] A colloquial use followed, of something great in number or degree, from 1800 in M. Edgeworth's Castle Rackrent according to the OED, which calls it chiefly Irish and American;^[3] Etymonline has it from 1811.^[2] From this came the adverb "very", recorded from before 1822 in the American South.^[3][2] Wright's dialect dictionary records the adjective for "great, considerable" in Ireland, Northumberland, Worcestershire and the Isle of Wight, the adverb in Ireland, the Isle of Wight and Devon, and, in Shetland, the senses "strong" of liquor and "plentiful".^[9]

Usage notes

Etymonline cites Thornton's American Glossary, which lists powerful, with monstrous, as much used by common people to mean "very", and Seth T. Hurd's Grammatical Corrector (1847), which calls it a "gross perversion" common in western Pennsylvania and also heard in the South, in such phrases as "a powerful weak man".^[2]
