'offal' originates from Middle English, specifically the word 'offal,' where 'of-' meant 'off' and 'fall' meant 'to fall.'

'offal' changed from the Middle English word 'offal' and has remained largely unchanged in modern English.

Initially, it meant 'that which falls off,' referring to waste or by-products, and over time it evolved into its current meaning of 'animal entrails used as food.'
