Old English Latin alphabet in the context of "Ligature (writing)"

Æ (lowercase: æ) is a character formed from the letters a and e, originally a ligature representing the Latin diphthong ae. It has been promoted to the status of a letter in some languages, including Danish, Norwegian, Icelandic, and Faroese. It was also used in both Old Swedish, before being replaced by ä, and Old English, where it was eventually dropped entirely in favour of a. The modern International Phonetic Alphabet uses it to represent the near-open front unrounded vowel (the sound represented by the 'a' in English words such as cat). Diacritic variants include Ǣ/ǣ, Ǽ/ǽ, Æ̀/æ̀, Æ̂/æ̂ and Æ̃/æ̃.

As a letter of the Old English Latin alphabet, it was called æsc, "ash tree", after the Anglo-Saxon futhorc rune ᚫ which it transliterated; its traditional name in English is still ash, or æsh (Old English: æsċ) if the ligature is included.

Modern English is written with a Latin-script alphabet consisting of 26 letters, with each having both uppercase and lowercase forms. The word alphabet is a compound of alpha and beta, the names of the first two letters in the Greek alphabet. The earliest Old English writing during the 5th century used a runic alphabet known as the futhorc. The Old English Latin alphabet was adopted from the 7th century onward—and over the following centuries, various letters entered and fell out of use. By the 16th century, the present set of 26 letters had largely stabilised:

There are 5 vowel letters (A, E, I, O, U) and 19 consonant letters—as well as 2 letters (Y and W) which may function as either type.

Anglo-Saxon runes or Anglo-Frisian runes are runes that were used by the Anglo-Saxons and Medieval Frisians (collectively called Anglo-Frisians) as an alphabet in their native writing system, recording both Old English and Old Frisian (Old English: ᚱᚢᚾᚪ, romanized: rūna, lit. 'rune'). Today, the characters are known collectively as the futhorc (ᚠᚢᚦᚩᚱᚳ, fuþorc) from the first six runes and their sound values. The futhorc was a development from the older co-Germanic 24-character runic alphabet, known today as Elder Futhark, expanding to 28 characters in its older form and up to 34 characters in its younger form. In contemporary Scandinavia, the Elder Futhark developed into a shorter 16-character alphabet, today simply called Younger Futhark.

Use of the Anglo-Frisian runes is likely to have started in the 5th century onward and they continued to see use into the High Middle Ages. By the 8th century, they were eventually overtaken by the Old English Latin alphabet introduced to Anglo-Saxon England by missionaries at the end of the 6th century. Futhorc runes were no longer in common use by the 11th century, but MS Oxford St John's College 17 indicates that fairly accurate understanding of them persisted into at least the 12th century.

Thorn or þorn (Þ, þ) is a letter in the Old English, Old Norse, Old Swedish and modern Icelandic alphabets, as well as modern transliterations of the Gothic alphabet, Middle Scots, and some dialects of Middle English. It was also used in medieval Scandinavia but was later replaced with the digraph th, except in Iceland, where it survives. The letter originated from the rune ᚦ (Thurisaz) in the Elder Futhark and was called thorn in the Anglo-Saxon and thorn or thurs in the Scandinavian rune poems. It is similar in appearance to the archaic Greek letter sho (ϸ), although the two are historically unrelated. The only language in which þ is currently in use is Icelandic.

It represented a voiceless dental fricative [θ] or its voiced counterpart [ð]. However, in modern Icelandic it represents a laminal voiceless alveolar non-sibilant fricative [θ̠], similar to th as in the English word thick, or a (usually apical) voiced alveolar non-sibilant fricative [ð̠], similar to th as in the English word the. Modern Icelandic usage generally excludes the latter, which is instead represented with the letter eth ⟨Ð, ð⟩; however, [ð̠] may occur as an allophone of /θ̠/, and written ⟨þ⟩, when it appears in an unstressed pronoun or adverb after a voiced sound.

Wynn or wyn (Ƿ ƿ; also spelled wen, win, ƿynn, ƿyn, ƿen, and ƿin), not to be confused with P, is a letter of the Old English alphabet, where it is used to represent the sound /w/. It was a continued use of the Anglo-Frisian Futhorc runes. Futhorc was the native alphabet of Old English before the Latin alphabet was adopted, and it was a sibling alphabet to the Younger Futhark alphabet that Old Norse used. Both alphabets come from Elder Futhark.
