'hyperkeratosis' originates from Greek, specifically the word 'hyperkeratosis,' where 'hyper-' meant 'over' and 'keratosis' referred to 'horny tissue or skin.'

'hyperkeratosis' changed from the Greek word 'hyperkeratosis' and eventually became the modern English word 'hyperkeratosis'.

Initially, it meant 'overgrowth of horny tissue,' and this meaning has largely remained the same in modern usage.
