'eyelid' originates from Old English, specifically the word 'ēagelid,' where 'ēage' meant 'eye' and 'hlid' meant 'cover.'

'ēagelid' transformed into the Middle English word 'eyelid,' and eventually became the modern English word 'eyelid.'

Initially, it meant 'cover for the eye,' and this meaning has largely remained the same in modern usage.
