Ḥ

Ḥ (minuscule: ḥ) is a letter of the Latin alphabet, formed from H with the addition of a dot diacritic.

Ḥ is used to represent the voiceless pharyngeal fricative (/ħ/) in Arabic, some Syriac languages (such as Turoyo and Sureth), Ancient Egyptian, and traditional Hebrew (whereas Hebrew-speaking Israelis and Ashkenazi Jews (though not strictly) have usually replaced the pronunciation of Ḥ in the respective eighth letter of the Semitic abjads, Ḥet with a voiceless uvular fricative (/χ/)).

This sound also exists in the Tigrinya and Somali languages, in Modern South Arabian languages and in smaller North East African languages.

Ḥ is used in Asturian to represent a voiceless glottal fricative (/h/) sound in Asturian words such as ḥou and ḥue, as well as some place names in the eastern part of Asturias (such as Ḥontoria and Villaḥormes).

[1] Ḥ represents visarga, the phone [h] in Sanskrit phonology in the International Alphabet of Sanskrit Transliteration.
