From Middle English hidous, from Anglo-Norman hidous, from Old French hideus, hydus (“that which inspires terror”), from earlier hisdos, from hisda (“horror, fear”), of uncertain and disputed origin. Probably from Frankish *egisda, *egisida (“terror, fright”), from Proto-Germanic *agisiþō (“horror, terror”), from Proto-Germanic *agisōną (“to frighten, terrorise”), from Proto-Germanic *agaz (“terror, fear”), from Proto-Indo-European *h₂egʰ- (“to frighten”). Cognate with Old High German egisa, egidī (“horror”), Old English egesa (“fear, dread”), Gothic 𐌰𐌲𐌹𐍃 (agis, “fear, terror”).
Alternative etymology cites possbile derivation from Latin hispidosus (“rugged”), from hispidus (“rough, bristly”), yet the semantic evolution is less plausible.
