Is “White in the Face” an Idiom?
While people often search for “white in the face” as an idiom, it is actually a literal physiological description rather than a figurative expression:
- The Physical Reaction: When a person experiences sudden terror, shock, or severe nausea, the body’s sympathetic nervous system triggers peripheral vasoconstrictionm, redirecting blood flow away from the skin and toward major muscle groups. This literally causes the facial skin to lose its natural color and appear drained or white.
- The Figurative Step: Phrases like white in the face or pale in the face describe that biological reaction directly. True idioms like white as a ghost, white as a sheet, or pale as death take that literal paleness and turn it into a poetic simile for dramatic emphasis.
Origin of “White as a Ghost”
Used since the mid-1800s, this idiom most likely comes from the association of ghosts with sheets. This association occurred because of the practice of wrapping the deceased in a burial shroud. In poorer families, a simple white sheet was used as a shroud, likely the sheet they the person died on. Ghosts had often been depicted as skeletons still wrapped in their shroud.
People later imagined the dead coming back as apparitions still shrouded in their death sheets. This led to people using sheets to dress themselves up as ghosts during Halloween and this image of a sheet-covered figure became associated with the appearance of ghosts. It is possible that ‘white as a sheet’ occurred first.
