The Spanish word 'payador' has an interesting etymology that traces back to the Latin personal name 'Pelagius'. This name evolved into the Spanish personal name 'Pelayo', which developed the nickname form 'Payo'. The term 'payador' was formed by combining 'Payo' with the Spanish agent suffix '-dor', literally meaning 'one who is Payo'. Over time, this term came to specifically refer to wandering folk singers and improvisational poets in South American countries, particularly Argentina and Uruguay.

A simpler related Spanish word is 'Payo', which was originally a nickname for people named Pelayo. While 'Payo' is now less commonly used as a nickname, it helps show how 'payador' developed - the folk singers may have been associated with this common nickname before it became a specific term for their profession.

While there aren't any commonly used English words directly related to 'payador', the name 'Pelagius' occasionally appears in English historical and religious contexts, referring to various historical figures including a British monk from the 4th-5th centuries. However, this connection is quite distant and wouldn't be particularly helpful for English speakers learning the word 'payador'.
