'andromeda' originates from Latin, specifically the word 'Andromeda', which was borrowed from Ancient Greek 'Andromēdē', the name of a princess in Greek mythology.

'Andromēdē' in Ancient Greek was adopted into Latin as 'Andromeda', and eventually became the modern English word 'andromeda'.

Initially, it referred to the mythological princess, but over time it also came to refer to the constellation, the galaxy, and a genus of plants.
