Chappy

Chappy is primarily used as a nickname, often derived from the word 'chaplain' or 'chapman' (a peddler or merchant). It can also be a playful diminutive of names like Charles or a descriptive nickname for someone who is 'happy' or 'lucky'. Its use as a standalone given name is rare and typically informal. The term 'chap' itself is an informal British English word for a man or boy, further contributing to the name's casual and friendly feel.
