Conceptismo is a literary movement of the Baroque period of Portuguese and Spanish literature. It began in the late 16th century and lasted through the 17th century.
Conceptismo is characterized by a rapid rhythm, directness, simple vocabulary, witty metaphors, and wordplay. In this style, multiple meanings are conveyed in a very concise manner, and conceptual intricacies are emphasised over elaborate vocabulary.
The most prominent writer of Castilian conceptismo is Francisco de Quevedo, who wrote with an ironic style and satirical wit. Other adherents of this style include Baltasar Gracián.
Conceptismo contrasts starkly with culteranismo, another movement of the Baroque period, which is characterized by ostentatious vocabulary, complex syntactical order, multiple, complicated metaphors, but highly conventional content. The best-known representative of Spanish culteranismo, Luis de Góngora, had an ongoing feud with Francisco de Quevedo in which they each criticized the other’s writing and personal life.
