Language Name

[stickmaker]

I'm working on a story set in an alternate universe where the empire established by Charles the Great lasted several centuries longer than in our world. As a result, much of western and central Europe speak a common language. Not French, not German, not Spanish, not Italian, but something related to all three. What would be a good name for this tongue?

Although Carolingian may be more accurate, perhaps Frankish might be closer to being a word in the language itself?
