What is the suffix of intentionally?

I thing it is ally since the root is intention am i correct?

Yes the root is intention. It becomes an adjective with the addition of the suffix "-al". Then it changes to an adverb with the suffix "-ly".

And there is no prefix am i corrects mrs. Sue?

You're right. There is no prefix.

Actually, the root is intent; "-ion" is also a suffix.

Yes, you are correct! The suffix of the word "intentionally" is "-ally." The root of the word is "intention," and the suffix "-ally" is added to form the adverbial form of the word. To determine the suffix of a word, you can break it down into its root word and any additional parts that are added to it. In this case, "intention" is the root, and "-ally" is the suffix.
