Ḥet or H̱et (also spelled Khet, Kheth, Chet, Cheth, Het, or Heth) is the eighth letter of many Semiticabjads (alphabets), including Phoenician, Syriacܚ, Hebrewח, Arabicح. In Berber (a non-Semitic language) it is rendered as ⵃ or Ḥ. Heth is usually represented in the Latin alphabet by ḥ.
Heth originally represented a voiceless fricative, either pharyngeal/ħ/, or velar/x/ (the two Proto-Semitic phonemes having merged in Canaanite). In Arabic, two corresponding letters were created for both phonemic sounds: unmodified ḥāʾح represents /ħ/, while ḫāʾخ represents /x/.
Ḥet is one of the few Hebrew consonants that can take a vowel at the end of a word. This occurs when patach gnuva comes under the Ḥet at the end of the word. The combination is then pronounced /-aχ/ rather than /-χa/. For example: פתוח (/ˌpaˈtuaχ/), and תפוח (/ˌtaˈpuaχ/).
Ḥet, along with Aleph, Ayin, Resh, and He, cannot receive a dagesh. As pharyngeal fricatives are difficult for most English speakers to pronounce, loanwords are usually Anglicized to have /h/. Thus challah (חלה), pronounced by native Hebrew speakers as /χala/ or /ħala/ is pronounced /halə/ by most English speakers, who cannot often perceive the difference between [h] and [ħ].
