bakeout
|bake-out|
/ˈbeɪkaʊt/
heat to remove (moisture/volatiles)
Etymology
'bakeout' originates from Old English elements, specifically the word 'bake' from Old English 'bacan' (meaning 'to cook by dry heat') combined with 'out' from Old English 'ūt' (meaning 'out').
'bake' changed from Old English 'bacan' to Middle English 'baken' and eventually to modern English 'bake'; combined with the adverb 'out', the compound 'bake-out' developed in modern English to describe the act of heating something so that volatiles go 'out' of it.
Initially, 'bake' meant 'to cook by dry heat'; over time the compound 'bakeout' evolved into a technical term meaning 'to heat something to remove moisture or volatile substances' rather than literal cooking.
