diaper
n. countablen. a piece of soft, absorbent material that a baby wears around their bottom to catch waste. You change it when it gets wet or dirty.
n. an absorbent garment worn by individuals who are unable to control their bladder or bowel movements, typically infants. Known as a 'nappy' in British English.
The baby needs a clean diaper.
Parents usually carry a bag filled with spare diapers and wet wipes whenever they leave the house with an infant.
Modern disposable diapers utilize super-absorbent polymers to lock away moisture, significantly reducing the incidence of skin irritation compared to traditional cloth versions.
From Middle English dyaper, diapre, dyapre, from Old French diapre, dyapre, a variant of dyaspre, diaspre (“ornamental silk cloth embellished with floral or decorative geometrical patterns”), from Medieval Latin diaspra, diasprum (“a type of rich, valuable silken cloth”), probably from Byzantine Greek δίασπρος (díaspros, “very white; pure white”, adjective), from δια- (dia-, “across”) + ἄσπρος (áspros, “white”).
Commonly used in North American English; the term 'nappy' is the standard equivalent in the UK and Australia.
