Spanish was a human language spoken in Spain, as well as large portions of both North and South America. Like French, Spanish was a romance language that had developed from the earlier Latin language.
Being from Mexico, Commander Estrella Miyakawa was fluent in Spanish. While at Starfleet Academy, Miyakawa attempted to teach fellow Cadet Jean-Luc Picard Spanish in exchange for his tutoring her in calculus. However Picard did not learn Spanish at the time, and Miyakawa failed the course. (TNG novel: The Devil's Heart).
