The Carolingian G or French G is one of two historical variants of the letter G which were in use in the Middle English alphabet; the other variant was the insular G or Irish G. The Carolingian G is named for the Carolingian minuscule script, an exemplar of its use.
The Carolingian G stands at the basis of the modern letter G, and eventually replaced the insular G as standard form for the letter. The Ᵹ survived for a while as the letter Ȝ before being removed from the English alphabet.
The Carolingian G is the standard letter form for G in all modern Latin alphabets.
