'bacon' originates from Old French, specifically the word 'bacun', where the element related to 'back' (meat from the back of an animal).

'bacon' changed from Old French 'bacun' into Middle English 'bacoun' and eventually became the modern English word 'bacon'.

Initially, it meant 'meat from the back (of an animal)', but over time it evolved into its current meaning of the cured pork product 'bacon'.
