There are important variations among the regions of Spain and throughout Spanish-speaking America. In some countries in Hispanophone America, it is preferable to use the word "castellano" to distinguish their version of the language from that of Spain, thus asserting their autonomy and national identity. In Spain, the Castilian dialect's pronunciation is commonly regarded as the national standard, although a use of slightly different pronouns called of this dialect is deprecated. More accurately, for nearly everyone in Spain, "standard Spanish" means, "pronouncing everything exactly as it is written," an ideal which does not correspond to any real dialect, though the northern dialects are the closest to it. In practice, the standard way of speaking Spanish in the media is "written Spanish" for formal speech, "Madrid dialect" (one of the transitional variants between Castilian and Andalusian) for informal speech.. The variety with the most number of speakers is Mexican Spanish, making up nearly a third of Spanish speakers.
