Pronunciation

  • IPA (Classical): [ˈɫak.sɪ.taːs][1]
  • IPA (Ecclesiastical): [ˈlak.si.tas][1]

Forms

laxitās f (genitive laxitātis); third declension[1]

Etymology

It is from Latin laxus (“loose, wide”) + -tās.[2][1] De Vaan reconstructs ⟨laxus⟩ as Proto-Italic ⟨*(s)lakso-⟩, from ⟨*slǵ-so-⟩ “weak, faint”, related to langueō.[3]

Earliest recorded meaning

The OLD's earliest citation is Cicero, of the roominess of a house.[2][4] Köbler dates Cicero 81–43 BC.[5]

Semantic evolution

It meant spaciousness, roominess, as of a house in Cicero; a wide area, expanse, and a relaxed condition, absence of strain, as in Seneca; and freedom of movement.[2][4][6] Lewis & Short call it rare but classical.[4]

British Medieval Latin used it for spaciousness.[7] English laxity (1520s) is from it through French.[8]

Timeline

  • 81–43 BC – Cicero uses it.[2][5]
  • 4 BC–65 AD – Seneca uses it of expanse and relaxation.[2][5]
