mighty

The word 'mighty' originates from the Old English adjective mihtiġ, a direct combination of the noun miht (meaning "power, strength, might") and the adjectival suffix -iġ (the ancestor of modern '-y'). The core noun 'might' itself descends from the Proto-Germanic root mahtiz, which is derived from the Proto-Indo-European root magh-, meaning "to be able, to have power." This ancient root also gave rise to words like 'may', 'machine', and 'magistrate' across different language branches. Thus, the literal construction "full of might" evolved seamlessly into its modern sense of possessing great power or force, with its informal adverbial use as an intensifier (e.g., "mighty fine") developing later from this core idea of impressive strength.
