The existence of multiple distinct cultures in Spain allows an analogy to be drawn to the United Kingdom. Using the term Spanish for someone of Spanish descent would then be expected to be equivalent to using Briton to describe someone descending from some part of the United Kingdom. Cultures within the United Kingdom, such as English, Irish, Scottish, and Welsh, would then correspond in this analogy to cultures within Spain such as Castilian, Catalan, Galician and Basque among others. In contrast with Spain, because of centuries of gradual and mutual consolidation across the Iberian Peninsula, such distinctions tend to be blurred. It is a subtle, yet important, distinction.
