Cañí is a Spanish adjective, which refers to the Romani people. La España cañí is a set phrase that refers to folkloric Spain and is sometimes used derogatorily. It must be distinguished from cani, a violent urban tribe of Spain. Note that in Spanish n and ñ are two different consonants with different pronunciation.
Cañí is the origin of the song name España cañí, meaning Gypsy Spain, a Spanish pasodoble often played at bullfights, and also known as the Spanish Gypsy Dance.
