Sure vs. Surely: Usage Guide

Most commentators consider the adverb sure to be something less than completely standard; surely is usually recommended as a substitute. Our current evidence shows, however, that sure and surely have become differentiated in use. Sure is used in much more informal contexts than surely. It is used as a simple intensive

I can never know how much I bored her, but, be certain, she sure amused me

—Norman Mailer

and, because it connotes strong affirmation, it is used when the speaker or writer expects to be agreed with.

it's a moot point whether politicians are less venal than in Twain's day. 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
