A lynx (/lɪŋks/;[2] plural lynx or lynxes[3]) is any of the four species (the Canada lynx, Iberian lynx, Eurasian lynx, or bobcat) within the medium-sized wild cat genus Lynx. The name lynx originated in Middle English via Latin from the Greek word λύγξ,[2] derived from the Indo-European root leuk- ('light, brightness')[4] in reference to the luminescence of its reflective eyes.[4]
