Pronunciation

  • Classical: [tɛˈnaː.kɪ.taːs][1]
  • Ecclesiastical: [teˈnaː.t͡ʃi.tas][1]

Forms

tenācitās f (genitive tenācitātis); third declension[1]

Etymology

It is formed from Latin tenāx + -tās, the quality of being tenāx (“holding fast”).[2][3] The adjective comes from teneō (“to hold”),[4][5] which de Vaan traces to Proto-Italic *t(e)nē- and Proto-Indo-European *tn-eh₁- (“to hold”).[6]

Earliest recorded meaning

Cicero (81–43 BC) has it first, in the De natura deorum, of animals that seize their food with the firm grip of their claws.[7][8][4]

Semantic evolution

The word was rare in Classical Latin.[7] Beside the literal “firm grip”, which Pliny the Elder also uses,[7][9] Livy applied it to money, in the sense “tight-fistedness, parsimony”.[7][9] In Christian Latin it came to mean steadfastness: Cyprian uses it for constancy,[10] and Jerome speaks of a retentive memory.[8] Medieval writers used it of the tightness of a grip or a bond, of the cohesion of mortar,[11] and figuratively of firm adherence to God's precepts.[11] English tenacity comes from it, partly through French.[5]

Timeline

  • 81–43 BC – Cicero uses it of the grip of animals' claws.[7][4]
  • 59 BC–17 AD – Livy uses it for parsimony.[7][4]
  • beginning of 3rd century–258 AD – Cyprian uses it for constancy.[10][4]
  • c. 383–419/420 AD – Jerome speaks of the retentiveness of memory.[8][4]
  • early 15th century – English tenacity is recorded, from Old French ténacité and directly from this word.[5]
