I've been asked what does my name mean?

The name Typhaine is a girl's name of French, Greek origin meaning "epiphany".
Typhaine (sometimes spelled Tiphaine) is an extremely rare girls name used occasionally in France, Switzerland and Jersey. The name derives from the Greek root words for epiphany. Typhaine might be considered an alternative to the tired Tiffany. It is from the Greek name Theophania.
