The Arabic letter ? (Arabic: ghayn or ?ayn) is the nineteenth letter of the Arabic alphabet, one of the six letters not in the twenty-two akin to the Phoenician alphabet (the others being th?', kh?', dh?l, d, '), it represents the sound or . In name and shape, it is a variant of ?ayn (?). Its numerical value is 1000 (see Abjad numerals). In the Persian language it represents ~ and is the twenty-second letter in the new Persian alphabet.
A voiced velar fricative /?/ or a voiced uvular fricative /?/ (usually reconstructed for Proto-Semitic) merged with ?ayin in most languages except for Arabic, Ugaritic, and older varieties of the Canaanite languages. Canaanite languages and Hebrew later also merged it with ?ayin, and the merger was complete in Tiberian Hebrew. The South Arabian alphabet retained a symbol for ?, ?. Biblical Hebrew, as of the 3rd century BCE, apparently still distinguished the phonemes ? /?/ and ? /?/, based on transcriptions in the Septuagint. For example, Gomorrah is represented in Hebrew as ?, which sounds like '?m?r?h in Modern Hebrew, but the Greek transcription of , Gomoras, suggests that the Hebrew lemma was then still pronounced as m?r?h.
The letter ghayn (?) is sometimes used to represent the voiced velar plosive /?/ in loanwords and names in Arabic; it is then often pronounced /?/, not /?/. Other letters, such as ?, ?, ?/? (also ?, ?, ?, ?, ?, instead of the original Arabic letters), can be used to transcribe in loanwords and names, depending on whether the local variety of Arabic in the country has the phoneme , which letter represents it if it does and on whether it is customary in the country to use that letter to transcribe . For instance, in Egypt, where ? is pronounced as in all situations, even in speaking Modern Standard Arabic (except in certain contexts, such as reciting the Qur'an), ? is used to transcribe foreign in virtually all contexts. In many cases, ? is pronounced in loanwords as expected (, not ) even though the original language had .
When representing the sound in transliteration of Arabic into Hebrew, it is written as .
In English, the letter ? in Arabic names is usually transliterated as gh>, ?>, or simply
