Is penta- a prefix or root?
Is -gon a suffix or root?
Thanks.

"Penta-" is a prefix and "-gon" is a suffix. Hmm... so what is the root of pentagon? Hmm.. Good question, BMO!  |

Maybe root can be a prefix or suffix.

In the Oxford Dictionary is says that penta- is a word that combined with other words means five. In chemistry it forms the names of compounds having five atoms or groups of a specified kind. e.g. pentachloride, pentoxide.
It comes from the greek pente= five.
-gon is likewise described as a combination form, forming nouns which denote plane figures with a specified number of angles. (pentagon, hexagon)
It comes from the greek noun gon = angle.
So, cutting to the chase I would say that in the case of pentagon penta- is the prefix and gon is the noun root. |
