'hider' originates from Old English, specifically the word 'hȳdan,' where 'hȳd-' meant 'to conceal or cover.'

'hȳdan' transformed into the Middle English word 'hiden,' and eventually became the modern English word 'hide,' from which 'hider' is derived.

Initially, it meant 'to cover or conceal,' and this meaning has largely remained the same in modern usage.
