Definition of tiffany in English:

tiffany

noun

  • [mass noun] Thin gauze muslin.

Origin

Early 17th century: from Old French tifanie, via ecclesiastical Latin from Greek theophaneia epiphany. The word is usually taken to be short for Epiphany silk or muslin, i.e., that worn on Twelfth Night, but may be a humorous allusion to epiphany in the sense ‘manifestation’ (because tiffany is semi-transparent).

Pronunciation:

tiffany
