Mat 11:9 But what did you go out to see? A prophet? Yes, I say to you, and more than a prophet.

"More" is perissoteros, which is a form of the word perissos, which means as an adjective when applied to people, "extraordinary" and "remarkable."

"Prophet" is prophetes, which means "one who speak for God and interpretes His will." It has the general sense of an interpreter, fortune-teller, and a herald.

Here Christ is saying that John was different and more than other prophets. Interestingly, he doesn't infer that he is the last or final prophet, in the Old Testament sense.
