'non-cooking' originates from the prefix 'non-' meaning 'not' and the word 'cooking' from Old English 'cōcian', meaning 'to prepare food by heating'.

'cōcian' transformed into the Middle English word 'coken', and eventually became the modern English word 'cook'.

Initially, 'cōcian' meant 'to prepare food by heating', and this meaning has largely remained the same in modern usage.
