Usage

What does nona- mean? Nona- is a combining form used like a prefix meaning “nine” or “ninth.” It is used in a number of scientific and other technical terms. In chemistry, nona- is specifically used to indicate nine atoms or nine groups of atoms in compounds, e.g., nonapeptide. Nona- comes from the Latin nōnus, meaning “ninth.” The word noon also derives from the Latin nōna hōra, the “ninth hour” from sunrise. 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.
