[Middle English unce, from Old French once, alteration of lonce, from Vulgar Latin *luncea, from Latin lynx, lync-, lynx, from Greek lunx; see leuk- in Indo-European roots.]

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English unce, from Old French, from Latin ūncia; see oi-no- in Indo-European roots.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From French once, from lonce ("lynx"), by false division (the l was thought to be the article), from Latin lynx, from Ancient Greek λύγξ ("lynx"). Interestingly, the taxon of the snow leopard is a Latinisation using the root of ounce (1).

  • See the last two WeirdNet definitions. I had no idea this word described a type of wild cat.

  • The OED marks its general 'medium-sized member of the cat family' definition as archaic, but not the specific definition 'the snow leopard, Panthera uncia'.

    Apparently this sense of 'ounce' appears in ounce stone, which is 'a precious stone mentioned by Pliny, now understood to have been amber'.

  • Last WeirdNet is beautiful: 'any of several large cats typically able to roar'.
