diaper (English)
Where does "diaper" come from?
The English word 'diaper' derives from the Middle English 'dyaper', which originally referred to a type of rich, valuable silk cloth[1][2]. This term traces back through the Old French 'diapre' and the Medieval Latin 'diaspra' to the Byzantine Greek adjective 'díaspros', meaning 'very white' or 'pure white'[1][2]. Over time, the meaning evolved from describing a specific ornamental fabric patterned with geometric or floral designs to denoting the absorbent garment that shares its name today[1].
