'aftershine' originates from Old English, specifically the word 'æfter' meaning 'after' and 'scīnan' meaning 'to shine'.

'æfter scīnan' transformed into the Middle English word 'aftershinen', and eventually became the modern English word 'aftershine'.

Initially, it meant 'the light that follows', but over time it evolved into its current meaning of 'the glow or light that remains in the sky after the sun has set'.
