Etymology: Roisten is an old spelling of the verb "roast," and its history runs through that verb. English took "roast" from Old French "rostir," which came from a Germanic root meaning to roast or grill over a fire. Cooking over flame was an ancient activity, so the sense has been part of English for centuries. Middle English spelled many words inconsistently, and "roisten" appears to be one of those variant spellings of the cooking verb. Its exact pathway and dates are uncertain, so it is safest to read it as a spelling of "roast" rather than a separate word with its own origin.
