The word "Musmon" is a variant of "Mouflon," which refers to a wild sheep of Europe and Asia. The correct spelling of the word is "mʊflɒn," with the first syllable pronounced as "mu" and the second syllable pronounced as "flon." However, the word "Musmon" is occasionally used as an alternate spelling, with the first syllable pronounced as "mus" instead of "mu." Despite this variation in spelling and pronunciation, both words refer to the same animal.
An animal said to be the sheep in a wild state, and the parent of the domestic sheep, about the size of the common ram, still found in the mountains of Corsica and Sardinia.
