tenacious

Etymology

It is borrowed from Latin tenāx (“holding fast, tough”), with the suffix -ous,^[2][3][4][5] from teneō (“to hold”),^[2][6][7] which the American Heritage Dictionary refers to Proto-Indo-European *ten-.^[6] Merriam-Webster Unabridged's cross-reference for the Latin verb is thin.^[8] Barnhart, Etymonline and Dictionary.com take the adjective rather as formed from tenacity with the same suffix,^[9][10][11] the noun being recorded probably before 1425, from Middle French ténacité and directly from Latin tenācitās.^[9] Johnson (1755) gave the Latin word as the source, and French tenace for the sense "cohesive".^[12]

Earliest recorded meaning

Holding together, cohesive, tough: 1607, in Topsell's Historie of Foure-footed Beastes.^[2][9][8] Etymonline dates the word to about 1600 in the sense "inclined to hold fast",^[10] and Hoad and Collins place it in the 16th century.^[7][13]

Semantic evolution

The physical senses came first, and the figurative ones soon followed.^[2] Cohesive (1607) was joined by sticky (1648) and by clinging tightly or grasping hard (1656), a sense first recorded in Blount's Glossographia.^[2] The application to people and minds appears from 1640 with holding persistently to a principle or method, and it extended to memory.^[2] Persistent or stubborn is also first recorded in Blount, in 1656.^[2][9] The noun tenacity had already meant persistence or obstinacy when it was first recorded.^[9] For a short time the adjective also meant close-fisted, from 1676, in Dryden's Aureng-Zebe, to 1686;^[2] and Johnson's entry (1755), with its quotations from Dryden, Locke and Arbuthnot, runs from unwillingness to let go of property or opinions through a retentive memory to cohesive matter.^[12] A later sense, chary of or averse to an action, lasted only from 1766 to 1811.^[2][3]
