Etymology

The word 'mightily' is built upon the Old English noun miht, meaning "power" or "strength," which itself descends from the Proto-Germanic root mahtiz. This root is further traced to the Proto-Indo-European base magh-, meaning "to be able, have power." The adjectival form 'mighty' emerged in Middle English, signifying "possessing might." The adverb 'mightily' was subsequently formed by appending the productive adverbial suffix '-ly' (from Old English -līce) to 'mighty,' with the connective 'i' easing pronunciation. Thus, the literal construction "in a manner of power" evolved to describe actions performed with great force, vigor, or to a very great degree.
