Carolingian G

Insular G (majuscule: Ᵹ, minuscule: ᵹ) is a form of the letter g somewhat resembling an ezh, used in the medieval insular script of Great Britain and Ireland. It was first used in the Roman Empire in Roman cursive, then it appeared in Irish half uncial (insular) script, and after it had passed into Old English, it developed into the Middle English letter yogh (Ȝ ȝ). Middle English, having reborrowed the familiar Carolingian g from the Continent, began to use the two forms of g as separate letters.
