Why is the abbreviation for the word number “no.” in English, even though there is no letter O in the word number?
The reason we use "no." here is because this abbreviation is borrowed from a Latin word--the abbreviation comes from Latin numero (meaning "by the number"), which does have an o in it. A similar thing happens with the "lb." abbreviation for "pound," which comes from Latin libra. More on reddit.com
