Who discovered the word hello?

The word "hello" doesn't have a single inventor or discoverer. It evolved over time from earlier forms of greeting. Here's a breakdown:

* Old English: The word "hāl" meant "whole" or "healthy" and was used as a greeting like "Hail!"

* Middle English: "Hāl" evolved into "halow" and then "hollo," which was a more casual greeting.

* Early Modern English: "Hallo" started to be used as a greeting in the 16th century.

* 19th Century: The spelling "hello" became more common.

So, the word "hello" was a natural progression of language, evolving from earlier greetings and eventually becoming the widely recognized word we use today.
