Since the Late Middle Ages, developed the sense “bad”, which became predominant over time, but did not displace the original one entirely. By the 17th century, attempts were made to reserve the i-variant specifically to the older meaning, but the semantic split between both forms was completed only during the 19th century. The adverbs and  (both “plainly, absolutely”) remain as relicts to this day.
