KK: /ˈhændˌbɪl/
A small printed paper that is given out to people, often used for advertising or promoting events.
The local theater handed out handbills to promote their new play.
Handbill → It is formed from "hand" (from Old English "hand", meaning the part of the body at the end of the arm) and "bill" (from Old French "billet", meaning a written note or document). A handbill is a written notice or advertisement that is distributed by hand.
Think of using your 'hand' to distribute a 'bill' or notice — that's why a handbill is a notice given by hand.
