Sure

I. adjective (surer; surest) Etymology: Middle English seur, sure, from Anglo-French seur, from Latin securus secure 1. obsolete safe from danger or harm 2. firmly established; steadfast Example: a sure hold 3. reliable, trustworthy Example: a sure friend 4. a. marked by or given to feelings of confident certainty Example: I'm sure I'm right b. characterized by a lack of wavering or hesitation Example: sure brush strokes Example: a sure hand 5. admitting of no doubt; indisputable Example: spoke from sure knowledge 6. a. bound to happen; inevitable Example: sure disaster b. bound, destined Example: is sure to win 7. careful to remember, attend to, or find out something Example: be sure to lock the doorsureness noun Synonyms: sure, certain, positive, cocksure mean having no doubt or uncertainty. sure usually stresses the subjective or intuitive feeling of assurance Example: felt sure that I had forgotten something. certain may apply to a basing of a conclusion or conviction on definite grounds or indubitable evidence Example: police are certain about the cause of the fire. positive intensifies sureness or certainty and may imply opinionated conviction or forceful expression of it Example: I'm positive that's the person I saw. cocksure implies presumptuous or careless positiveness Example: you're always so cocksure about everything. II. adverb surely Usage: 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 Example: 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 Example: 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 Example: he sure gets them to play — D. S. Looney. Surely, like sure, is used as a simple intensive Example: 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 Example: 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 Example: surely a book on the avant-garde cannot be so conventional — Karl Shapiro.
