That means 12 o’clock noon was originally 3 p.m!The Greek word for “nine” is ennéa, source of the combining form ennea-, which you can learn more about in our Words That Use article for the form.What are variants of nona-?When combined with words or word elements that begin with a vowel, nona- becomes non-, as in nonyl alcohol.However, in a great many more instances, the letters non- at the beginning of a word are the prefix non-, meaning "not," as in nonabrasive or nonacademic.
