What does aghast mean?
Aghast describes someone struck with overwhelming horror, shock, or dismay — a reaction so strong it seems to stop them in their tracks. The word functions only as an adjective and appears almost exclusively in predicative positions: one is aghast, stands aghast, or stares aghast, rather than describing something as an 'aghast expression'. Its connotations lean toward moral outrage or appalled disbelief rather than simple astonishment; witnesses to scandal, cruelty, or catastrophe are typically said to be aghast. The register is somewhat formal and literary, lending gravity to journalism, fiction, and rhetoric. Etymologically rich, aghast descends from Middle English and ultimately connects to Old English roots shared with 'ghost' and 'ghastly', reflecting an older sense of being terrified as if by a spirit. For writers seeking a vivid, weighty alternative to 'shocked' or 'horrified', aghast remains a precise and evocative choice.

"Aghast" literally once meant "frightened to death" — its Old English root *gāst* is the same word that gives us "ghost."

Etymology of aghast
Aghast derives from Middle English 'agast', the past participle of the now-obsolete verb 'gasten', meaning to terrify or frighten. That verb traces back to Old English 'gāstian', formed on 'gāst', meaning spirit or ghost — the same root that yields modern 'ghost' and 'ghastly'. The spelling with '-h-' became standard in later centuries, and by early modern English the word had settled into its current sense of being struck with horror or shocked amazement.
How aghast is actually used
Predominantly used in formal or literary registers; almost always appears predicatively ('was aghast', 'stood aghast') rather than attributively. It carries a strongly negative connotation of moral outrage or horrified disbelief rather than mere surprise.
