'bakepan' originates from English, specifically the compound of 'bake' and 'pan', where 'bake' meant 'to cook by dry heat' and 'pan' meant 'a shallow metal container'.

'bake' comes from Old English 'bacan' and 'pan' from Old English 'pann'; the phrase 'bake pan' appeared in Modern English and was later sometimes written as the single word 'bakepan'.

Initially it literally combined the words 'bake' + 'pan' to mean 'a pan used for baking'; over time the compound has remained largely literal with the same basic meaning.
