In Byzantine Greek, relating to evening or the west; occurring or existing in the evening time.
From Greek hesperinos, from hespera (evening), related to Hesperus (evening star). The root connects to Indo-European *spe- meaning 'to stretch out' or 'to extend.'
This Greek word is where 'hesper-' words come from, and it literally means 'of the evening'—perfect for naming a star that only appears at sunset and sunrise!
