Which three language traditions make up Spanish literature?

Spanish literature comprises literary works produced in Spain, which are categorized into three major language traditions:

• Castilian: The primary language of Spanish literature, which originated in the 9th century and became the official language of Spain.12
• Catalan: A language tradition with historical ties to Provençal and the poetic forms of the troubadours.13
• Galician: A language tradition that served as the conventional medium for courtly lyric until the 15th century and experienced a modern revival in the 19th century.145

These divisions represent the primary linguistic branches of the body of work produced within Spain.1
