Spanish or Castilian?
The official language of Spain is Spanish. Obviously. It was at the hands of the Spaniards that the use of Spanish spread throughout America. But many people refer to the main language spoken in Spain as Castilian. The term Castilian is often used as a synonym for European Spanish, and according to the Fundéu (Fundación del Español Urgente, or Foundation of Emerging Spanish) this is a valid synonym. However, using the term Spanish is recommended since it is less ambiguous. It is preferable to limit the use of the term Castilian when referring to the Romance dialect of the Middle Ages. Another term used to refer to the Spanish used in the country of Spain is Castilian Spanish.

Other Spanish Dialects
What qualifies as a Spanish dialect? To be able to classify as a dialect, you must take into account the following characteristics: it does not have its own literature, it is derived from a formally recognized language, its expressions and sounds are not so different, and that speakers of different dialects derived from the same language do not understand each other. A dialect also contains a familiar, colloquial lexicon.
Some of the dialects spoken in Spain are:
As these and other Spanish dialects have no literature, the need for translation services into these dialects is low if it exists at all. However, marketing and advertising in regions where a certain dialect is spoken is will be done in the language and tone of the locals. Ad agencies that work in those areas have the linguistic resources to capture the words and sounds of the dialect.
