The Spanish word 'changa' meaning 'odd job' or 'temporary work' comes from Galician-Portuguese, where it had the same meaning. This term is particularly common in Latin American Spanish to refer to casual or temporary employment.

A related term in modern Spanish is 'changador', which refers to a person who does odd jobs or works as a porter, particularly in some South American countries. The diminutive form 'changuita' is also commonly used to refer to a small job or minor task.

While there aren't direct English cognates of 'changa', English speakers might find it helpful to think of similar concepts like 'gig' (as in 'gig economy') or 'odd job' which convey a similar meaning of temporary or casual work.
