Building upon Varro, most modern Latinists derive this word from ūnicus (“unique”) +‎ -ia, itself from ūnus (“one”) (from Proto-Indo-European *óynos) in the sense of twelfths making up the base unit of various ancient systems of measurement.

Following Heron of Alexandria, Weiss instead postulates a borrowing from Ancient Greek ὀγκία (onkía, “uncia”), from ὄγκος (ónkos, “weight”); he considers the loss of medial /i/ necessitated by the traditional etymology unproblematic but the derivation from "unique" semantically implausible.

発音

• (Classical Latin) IPA: [ˈuːŋ.ki.a], [ˈʊŋ.ki.a]
• (modern Italianate Ecclesiastical) IPA: [ˈun̠ʲ.t͡ʃi.a]

It is uncertain whether long or short U occurred in ū̆ncia and in its compounds ending in -ū̆nx, -ū̆ncis. If a connection with ūnus is accepted, that word has long ū and Bennett (1907) thus marks long ū in ūncia, quīncūnx, quīncūncis. However, originally long vowels could be shortened in Latin before consonant clusters starting in resonant consonants such as [ŋ] (this shortening can be referred to as "Osthoff's Law", which is the name of a similar sound change that occurred in Greek). If Weiss' alternate etymology is accepted, there is no reason to posit a long vowel in this word; in any case, a Latin form ŭncia with a short vowel is represented by French once, Italian oncia, Spanish onza among others.

From Middle French once (“lynx, wild cat”) under influence from once (Latin uncia, “ounce”), from false division of Old French lonce (“lynx”) mistaking its initial l for the article l', from Vulgar Latin *luncea possibly via Italian lonza, from Latin lynx, from Ancient Greek λύγξ (lúnx, “lynx”). First used in reference to the snow leopard by Johann Christian Daniel von Schreber in 1777 as Felis uncia.
