Pronunciation

  • IPA (Classical): [ɫaː.tɪˈtuː.doː][1]
  • IPA (Ecclesiastical): [la.tiˈtuː.do][1]

Forms

lātitūdō f (genitive lātitūdinis); third declension[1]

Etymology

It is from Latin lātus (“broad, wide”) + -tūdō.[2][1] Lātus is *slāto-; its further origin is uncertain.[3] In the geographical sense it is a calque of Ancient Greek κλίμα (klíma).[1]

Earliest recorded meaning

Köbler's first source is Cato (234–149 BC).[4] Cato gives the width of a pressing room.[2]

Semantic evolution

It meant breadth or width, as Caesar's width of a ditch and camp stretching more than eight miles in breadth, and Cicero's “immensity of breadths, lengths, heights”.[2][5] It meant broadness, as the broad shoulders of oxen in Cicero, and extent or size.[2][1]

Cicero uses verborum latitudo of a broad, drawling pronunciation, and it also meant fullness of style.[2][6] As an astronomical and geographical term it meant latitude.[2][1] English latitude was borrowed in the late 14th century, first meaning “breadth”.[7]
