'unbaked' originates from the prefix 'un-' meaning 'not' and the verb 'bake', which comes from Old English 'bacan', meaning 'to cook by dry heat'.

'bake' changed from the Old English word 'bacan' and eventually became the modern English word 'bake'.

Initially, 'bake' meant 'to cook by dry heat', and this meaning has largely remained the same in modern usage.
