Letter of the Latin alphabet
the Middle English letter ȝ

The letter yogh (ȝogh) (Ȝ ȝ; Scots: yoch; Middle English: ȝogh) was used in Middle English and Older Scots, representing y and various velar phonemes. It was derived from the Insular form of the letter g, Ᵹᵹ. In Middle English writing, tailed z came to be indistinguishable from yogh. In Middle Scots, the character yogh became confused with a cursive z and the early Scots printers often used z when yogh was not available in their fonts. Consequently, some Modern Scots words have a z in place of a yogh—the common surname Menzies was originally written Menȝies (pronounced mingis). Yogh is shaped similarly to the Cyrillic letter З and the Arabic numeral 3, which are sometimes substituted for the character in online reference works. There is some confusion about the letter in the literature, as the English language was far from standardised at the time. Capital Ȝ is represented in Unicode by code point , and lower case ȝ by code point .

In Modern English yogh is pronounced /j//ɒ//ɡ/, /j//ɒ//x/ using short o or /j//oʊ//ɡ/, /j//oʊ//k/, /j//oʊ//x/, using long o. It stood for /ɡ/ and its various allophones—including and the voiced velar fricative —as well as the phoneme /j/ ( in modern English orthography). In Middle English, it also stood for the phoneme and its allophone [ç] as in ("night", in an early Middle English way still often pronounced as spelled so: ), and also represented the phonemes /j/ and /dʒ/. Sometimes, yogh stood for or , as in the word , "yowling". In Middle Scots, it represented the sound in the clusters , and written lȝ and nȝ. Yogh was generally used for rather than y. In medieval Cornish manuscripts, yogh was used to represent the voiced dental fricative , as in its , now written , pronounced .

The original Germanic g sound was expressed by the gyfu rune in the Anglo Saxon futhorc (which is itself sometimes rendered as ȝ in modern transliteration). Following palatalization, both gyfu and Latin g in Old English expressed the sound before front vowels. For example, "year" was written as gear, even though the word had never had a g sound (deriving from Proto Germanic *jērą). With the re introduced possibility of a sound before front vowels, notably in the form of loanwords from the Old Norse (such as gere from Norse gervi, Modern English gear), this orthographical state of affairs became a source for confusion, and a distinction of "real g" from "palatalized g" became desirable. In the Old English period, ᵹ was simply the way Latin g was written in the Insular script introduced at the Christianisation of England by the Hiberno Scottish mission. It only came to be used as a letter distinct from g in the Middle English period, where it evolved in appearance into ȝ, now considered a separate character.

In the 14th century, the digraph gh arose as an alternative to yogh for /x/, and eventually overtook yogh in popularity; still, the variety of pronunciations persisted, as evidenced by cough, taught, and though. The process of replacing the yogh with gh was slow, and was not completed until the arrival of printing presses (which lacked yogh) in England around the end of the fifteenth century. Not every English word that contains a gh was originally spelled with a yogh: for example, spaghetti is Italian, where the h makes the g hard (i. e., instead of ); ghoul is Arabic, in which the gh was
The medieval author Orm used this letter in three ways when writing Early Middle English. By itself, it represented , so he used this letter for the y in "yet". Doubled, it represented , so he ended his spelling of "may" with two yoghs. Finally, the digraph of ȝh represented
In the late Middle English period, yogh was no longer used: niȝt came to be spelled night. Middle English re imported G in its French form for (As a further side note, French also used to represent in words like voyage and yeux).
