From Middle English agheful, awfull, auful, aȝefull, equivalent to awe + -ful. Compare Old English eġeful, eġefull (“terrifying; awful”). The “very bad” sense is a pejorative semantic shift from the original sense of “awe-inspiring”.
Often used as an intensifier in the adverbial form 'awfully' to mean 'very'.
