NONAGON

Nonagon

In geometry, a nonagon is a nine-sided regular polygon. The name "nonagon" is a prefix hybrid formation, from Latin, used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century. The name "enneagon" comes from Greek enneagonon, and is arguably more correct, though somewhat less common than "nonagon".
