O artigo pretende mostrar o aspecto inovador do léxico das Cantigas de Santa Maria (CSM). Além de um maior número de vocábulos que outros cancioneiros, as CSM apresentam muitas palavras cultas e semicultas, que ampliaram as áreas semânticas abrangidas pelo léxico do galego-português do século XIII.
This paper aims at demonstrating the innovative aspect of the Cantigas de Santa Maria's vocabulary. Besides a bigger number of vocabulary items than other medieval Portuguese song-books, the CSM presents many cult and "semi-cult" words, which increase the semantic areas covered by the lexicon of Galician-Portuguese of the 13th Century. Therefore, the Cantigas de Santa Maria make a vast linguistic and cultural contribution to the medieval Portuguese.
