In plain English: A diaper is an absorbent cloth or disposable pad worn by babies and young children to catch their urine and stool so they stay clean and dry.
"The baby needs a fresh diaper after every feeding."
Usage: Use this word to describe the absorbent garment worn by infants, not the historical textile with a diamond weave which is now obsolete in modern English. It functions as both a noun for the item itself and a verb meaning to dress an infant or animal in one.
To put diapers on someone.
"The nurse carefully diapered the newborn after checking that he was warm and dry."
In plain English: To diaper means to put on disposable underwear for someone who cannot control their bladder or bowels.
"The baby was in such distress that she had to diaper him immediately before we could leave."
The word diaper comes from Middle English via Old French and Medieval Latin, originally referring to an ornamental silk cloth with decorative patterns. Its ultimate origin is a Byzantine Greek term meaning "very white," which described the pure color of these valuable fabrics before they were adopted into modern usage for absorbent clothing.
