Combination name; likely of plus Quan
Delquan is a modern American invention, likely created by combining the Spanish or French prepositional prefix 'Del' (meaning 'of the') with the name Quan. Quan itself often has roots in Chinese meaning 'spring' or 'authority', but in this context, it is typically used for its rhythmic, contemporary sound.
