In Hebrew orthography the rafe, or more commonly spelt raphe (Hebrew: רָפֶה‎ pronounced [ʁaˈfe]), is a diacritic (⟨ ֿ‎ ⟩), a subtle horizontal overbar placed above certain letters to indicate that they are to be pronounced as fricatives. In some siddurs (e.g. those printed by ArtScroll) a diacritical symbol, typographically the same as the rafe, but utterly unrelated, is used to mark instances of "moving sheva" (Shva Na). The rafe is similar in function to the buailte (dot above, denoting lenition) in the old-style Irish alphabet.
