What does nappy mean?
Nappy has several related uses, but its best-known meaning is the British English noun for a disposable diaper: an absorbent garment worn by babies and young children. In this sense, it appears in everyday expressions such as “change a nappy” and “put on a nappy.” American English normally uses “diaper” instead, although “nappy” is also used in some informal or nostalgic contexts. The word can also refer, especially in British and American English, to tightly curled hair, a usage that can be derogatory when applied to a person. As an adjective, nappy describes something covered with a soft nap or having a fuzzy, springy texture. Its history is connected with “nap,” the fine downy surface found on cloth, and with the related vocabulary of “napkin.” The varied meanings make nappy a useful example of how a familiar word can shift between practical household language, regional vocabulary, and older descriptive or potentially insulting terminology.

In American English, “diaper” is the usual term. The British sense is also common in other Commonwealth varieties.
A hairstyle or mass of tightly curled hair, especially in a usage that may be derogatory.
"The description of his hair as nappy was immediately recognised as insulting."
This use is chiefly associated with British English, though it is also known in American English. It is often considered offensive when used to characterize a person.

In British English, nappy is the everyday word for a baby's disposable diaper; in American English, the same word can describe tightly curled hair, though that use may sound derogatory.

Where does nappy come from?
The word “nappy” developed from “nap,” meaning a soft, downy or fuzzy surface, with the familiar suffix “-y.” In its baby-care sense, it became established in British English as a name for a cloth or disposable diaper, probably through the older vocabulary of cloth napkins and related infant-care terms. Its use for tightly curled hair also reflects the idea of hair having a dense, springy or downy texture. The English “napkin” has a related history through French napper and Latin napus, a small tablecloth or towel.
