flabbergasted (English)
Where does "flabbergasted" come from?
The origin of 'flabbergasted' remains somewhat mysterious, though it likely emerged in the late 18th century as a playful coinage combining the sound of 'flabby' with the word 'aghast.' It gained popularity to describe a state of being so shocked that one feels physically collapsed or 'blown away,' eventually evolving from a colloquialism into our modern term for being utterly astounded.
