I'm having trouble making sense of all the theories about the spread of Celtic languages and culture(s). How does the Atlantic Fringe hypothesis of Celtic material culture (starting from Iberia, moving eastward) fit with the purported westward spread of Celtic languages (& IE languages in general)?

There's certainly much more to be told about this complex, and unresolved, question but you might find some clarification in this previous answer.

Where did the Celts REALLY originate from?
