Orthography
Old English was first written in runes (futhorc) but shifted to a (minuscule) half-uncial script of the Latin alphabet introduced by Irish Christian missionaries from around the 9th century. This was replaced by insular script, a cursive and pointed version of the half-uncial script. This was used until the end of the 12th century when continental Carolingian minuscule (also known as Caroline) replaced the insular.
The letter ðæt ⟨ð⟩ (called eth or edh in modern English) was an alteration of Latin ⟨d⟩, and the runic letters thorn ⟨þ⟩ and wynn ⟨ƿ⟩ are borrowings from futhorc. Also used was a symbol for the conjunction and, a character similar to the number seven (⟨⁊⟩, called a Tironian note), and a symbol for the relative pronoun þæt, a thorn with a crossbar through the ascender (⟨ꝥ⟩). Macrons ⟨¯⟩ over vowels were rarely used to indicate long vowels. Also used occasionally were abbreviations for a following m or n. All of the sound descriptions below are given using IPA symbols.
