sure vs. surely
Most commentators consider the adverb sure to be something less than completely standard; surely is usually recommended as a substitute.

But they're sure as the devil more intrusive — Alan Abelson he sure gets them to play — D. S. Looney Surely, like sure, is used as a simple intensive I surely don't want to leave the impression that I had an unhappy childhood — E. C. Welsh but it occurs in more formal contexts than sure. Unlike sure it may be used neutrally—the reader or hearer may or may not agree it would surely be possible, within a few years, to program a computer to construct a grammar — Noam Chomsky and it is often used when the writer is trying to persuade. surely a book on the avant-garde cannot be so conventional — Karl Shapiro
