Afton comes from an English surname, a habitational name for someone who came from a place called Afton. It originated from the name of a river in Ayrshire, Scotland (also known as Afton Water) which was popularized by a poem written by Scottish poet Robert Burns (1759-1796) titled ‘Sweet Afton’ (1791). The meaning of the word is unknown but it may possibly be derived from a Gaelic word meaning “river”.
Afton is also a Swedish word meaning “evening; eventide” descended from Proto-Germanic *ēbanþs (evening) derived from a PIE root word.
Origin: uncertain, Proto-Indo-European
