IPA: /ˈhændaʊt/
KK: /ˈhændaʊt/
A piece of paper or a document given to people for free, often containing information or details about a topic, event, or organization.
The teacher gave each student a handout with important information about the upcoming exam.
Handout → It is formed from "hand" (from Old English "hand", meaning the end part of a person's arm) and "out" (meaning away from the inside). The word "handout" refers to something given out or distributed, typically for free.
Think of something being given 'away' ('out') by a 'hand' — that's why a handout is something distributed.
