Gh is a digraph found in many languages.

In Latin-based orthographies[edit]

English[edit]

In English, gh historically represented [x] (the voiceless velar fricative, as in the Scottish Gaelic word Loch), and still does in lough and certain other Hiberno-English words, especially proper nouns. In the dominant dialects of modern English, gh is almost always either silent or pronounced /f/ (see ough). It is thought that before disappearing, the sound became partially or completely voiced to [ɣx] or [ɣ], which would explain the new spelling - Old English used a simple h - and the diphthongization of any preceding vowel.

It is also occasionally pronounced [ə], such as in Edinburgh.

When gh occurs at the beginning of a word in English, it is pronounced /ɡ/ as in "ghost", "ghastly", "ghoul", "ghetto", "ghee" etc. In this context, it does not derive from a former /x/.

American Literary Braille has a dedicated cell pattern for the digraph gh (dots 126, ⠣).

Esperanto[edit]

In Esperanto orthography, gh can be used when printers lack type for ĝ.

Galician[edit]

In Galician, it is often used to represent the pronunciation of gheada.

Irish[edit]

In Irish, gh represents /ɣ/ (the voiced velar fricative) and /j/ (the voiced palatal approximant). Word-initially it represents the lenition of g, for example mo ghiall [mə jiəl̪ˠ] "my jaw" (cf. giall [ɟiəl̪ˠ] "jaw").

Italian and Romanian[edit]

In Italian and Romanian, gh represents /ɡ/ (the voiced velar plosive) before e and i.

Malay[edit]

In the Malay and Indonesian alphabet, gh is used to represent the voiced velar fricative (/ɣ/) in Arabic origin words.

Maltese[edit]

The Maltese language has a related digraph, . It is considered a single letter, called għajn (the same word for eye and spring, named for the corresponding Arabic letter 'ayin). It is usually silent, but it is necessary to be included because it changes the pronunciation of neighbouring letters, usually lengthening the succeeding vowels. At the end of a word (when not substituted by an apostrophe), it is pronounced [ħ]. Its function is thus not unlike modern English gh, except that the English version comes after vowels rather than before like Maltese (għajn would come out something like ighn if spelled as in English).

Tlingit[edit]

In Canadian Tlingit gh represents /q/, which in Alaska is written ǥ.

Taiwanese[edit]

In Daighi tongiong pingim, gh represents /ɡ/ (the voiced velar stop) before a, e, i, o, and u.

Uyghur[edit]

GH gh, a digraph in Uyghur(Uyghur Latin script), GH gh represents [ʁ] in Uyghur Latin script.

In romanization[edit]

In the romanization of various languages, gh usually represents the voiced velar fricative (/ɣ/). Like kh /x/, gh may also be pharyngealized, as in several Caucasian and Native American languages. In transcriptions of Indo-Aryan languages such as Sanskrit and Hindi, as well as their ancestor, Proto-Indo-European, gh represents a voiced velar aspirated plosive /ɡʱ/ (often referred to as a breathy or murmured voiced velar plosive)
