Etymology
Origin of hello
First recorded in 1865–70; variant of hallo
Explanation
Hello! Hi! How are you doing? Hello is a salutation or greeting commonly used to begin conversations or telephone calls. Hello has been used as an English greeting since the 19th century. Most agree that it is related to the older French exclamation “Holà” — which means essentially “Ho there!” — like you might say to a horse to tell it to stop. Nowadays it’s still used to get someone’s attention but instead of stopping you’re starting something — usually a chat. Hallo and Hullo are variations of Hello used by British English speakers.
