From Middle English mightili (“with might, powerfully, strongly; forcefully, violently; greatly; etc.”), from Old English meahtiglice (“with might, powerfully, mightily”), from meahtiġ, mihtiġ (“powerful, mighty”) + -līċe (suffix forming adverbs). Mihtiġ is derived from Proto-Germanic mahtīgaz (“mighty”), from mahtiz (“force, strength; ability, power”) (ultimately from Proto-Indo-European megʰ- (“to be able”)) + -gaz (suffix with the sense ‘being; doing; having’ forming adjectives). By surface analysis, mighty + -ly (suffix forming adverbs).
