Pronunciation

  • Classical: [ˈkʷan.tɪ.taːs][1]
  • Ecclesiastical: [ˈkʷan.ti.tas][1]

Forms

quantitās f (genitive quantitātis); third declension[1]

Etymology

It is from Latin quantus (“how great, how much”) + -tās.[2][1][3] It was made as a translation of Ancient Greek ποσότης (posótēs, “quantity”), from πόσος (pósos, “how great? how much?”),[4][1] like quālitās.[1] Wiktionary credits the coinage to Cicero,[1] although the earliest citation the OLD gives is from Vitruvius.[2]

Earliest recorded meaning

The OLD's and Köbler's first author is Vitruvius, who uses it of size, for example the size of the intervals between musical tones.[2][3]

Semantic evolution

Lewis & Short think it perhaps only post-Augustan.[5] Quintilian uses it as one of the ten categories, divided into how large and how many a thing is, and of the volume of the voice.[2][5] Pliny the Elder has it for an amount of moisture, and Apuleius for a large amount.[2]

The jurists used it for a specified amount, above all a sum of money,[2][5] and the logicians for the quantity of a proposition, whether universal or particular.[5][6] Boethius and Cassiodorus use it of the philosophical category.[7] Medieval Latin used it of the size of bodies, land and time, and in music of the duration of a note.[8]

It was borrowed into English as quantity in the early 14th century, partly through Old French ⟨quantite⟩;[4] Italian quantità also continues it.[7][4]
