Selected source glosses provide context, not a complete modern definition inventory

From Middle English agast, agasted, past participle of agasten (“to terrify”), from Old English a- (compare with Gothic 𐌿𐍃- (us-), German er-, originally meaning "out") + gæstan (“to terrify, torment”): compare Gothic 𐌿𐍃𐌲𐌰𐌹𐍃𐌾𐌰𐌽 (usgaisjan, “to terrify”, literally “to fix, to root to the spot with terror”); akin to Latin haerere (“to stick fast, cling”). By surface analysis, a- + ghast/gast. See gaze.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
