'ember' originates from Old English, specifically the word 'æmerge,' where 'æ-' meant 'burn' and 'merge' meant 'glow.'

'æmerge' transformed into the Middle English word 'ember,' and eventually became the modern English word 'ember.'

Initially, it meant 'burning coal or wood,' but over time it evolved into its current meaning of 'glowing remains of a fire.'
