'axunge' originates from Latin, specifically the word 'axungia', where the original term denoted 'fat' or 'grease'.

'axunge' passed into Middle English from Medieval/Latin 'axungia' and was used in older English texts; it is now archaic.

Initially, it meant 'animal fat or grease', and while that basic meaning has been preserved, the word itself became obsolete in modern English.
