Mundaka
Others have related the name "Mundaca" to a stock of Basque toponyms with the endings "-aka", "-eka", "-ika", which are especially abundant in Biscay and which can be linked with the Celto-Italic suffix "-aka". To some the origin of the name would be much older and it could be traced back to an era in which Vizcaya could have been populated by a Celtic people.
