Etymology

The heraldic potent is inherited from Middle English potente (“crutch”), borrowed from Anglo-Norman potente (“crutch”), also Middle French of Flanders and Picardy, recorded in Old French in the 13th century,[3][5] apparently an alteration of potence (“crutch, gibbet”),[3][2][6][1] perhaps through an unrecorded variant Medieval Latin *potenta of potentia (“power”),[3] which in Medieval Latin also meant a crutch.[6][5] In English its development was influenced by the noun and adjective potence.[3]

Earliest recorded meaning

A crutch, or a staff with a crosspiece to lean on: the OED's first example is from the Exchequer accounts of 1348.[3] Dictionary.com dates the Middle English word to 1325–75.[5]

Semantic evolution

From the crutch came the figurative sense "a support, a stay", recorded in Lydgate's Fall of Princes (?a1439) and rare after the 15th century;[3][2] in Scots the word was used about 1550 for a gibbet.[3] In 1688 Randle Holme used it for a cross handle shaped like the head of a crutch, and for the T-shaped figure of heraldry.[3] A cross whose arms end in such T-shapes is a cross potent, recorded in a Scottish heraldic manuscript before 1586,[3] about 1586 in Merriam-Webster;[1] potent counter potent, a heraldic fur made of rows of upright and inverted T-shapes placed end to end, is recorded from 1708.[3][1]

Etymology

The adjective meaning "powerful" is borrowed from Latin potēns (“powerful, mighty, effective”),[3][7][8][9][10] the present participle of possum (“to be able, be powerful”).[7][11][12][13] Barnhart and Hoad explain it as the participle of an unrecorded older verb Latin *poteō (“to be powerful”), from potis (“powerful, able”); because the infinitive of possum was a contraction of a phrase meaning "to be powerful" (potis with sum (“to be”)), potēns came to serve as its participle.[9][10][11][1] The Latin adjective goes back to Proto-Indo-European *poti- (“powerful; lord”).[7][8] In post-classical Latin potēns was also said of strong wine, in a 13th-century British source.[3] French had potent in 1607, and Spanish potente is recorded from the 13th century.[3]

Earliest recorded meaning

Of a person or thing: powerful, having great authority or influence, mighty.[3][9] Barnhart dates the word probably to about 1425;[9] the OED's first example is from the Speculum Sacerdotale (a1500, composed perhaps about 1425),[3] and Etymonline gives the early 15th century.[7] Dictionary.com dates it to 1490–1500.[5]

Semantic evolution

The general sense is now chiefly literary.[3] From it the word was applied to arguments and ideas that convince (1609, in Shakespeare's Troilus and Cressida),[3] and to drugs and drinks with a strong effect, from 1603 in Drayton.[3][2] The sexual sense, of a man able to have intercourse, is recorded from before 1633 in Archbishop Abbot's Case of Impotency, the opposite of impotent.[3] Johnson (1755) defined the adjective as "powerful; forcible; strong; efficacious".[14] Used as a noun, potent meant a power (1512), a powerful person or potentate (1568–1704) and a military warrant (1622–1728), all now obsolete;[3][1] a 20th-century American noun use, a potion or herbal remedy, dates from 1902.[3]
