[Middle English, from Old French, from Vulgar Latin *certānus, from Latin certus, past participle of cernere, to determine; see krei- in Indo-European roots.]Synonyms: certain, inescapable, inevitable, sure, unavoidable
These adjectives mean impossible to avoid or evade: soldiers who knew they faced certain death; facts that led to an inescapable conclusion; an inevitable result; sudden but sure retribution; an unavoidable accident. See Also Synonyms at sure.Usage Note: It is often claimed that certain is an absolute term like unanimous or paramount and cannot be modified; something is either certain or it is not. However, a majority of the Usage Panel accepted the construction Nothing could be more certain as early as 1965, and phrases such as fairly certain and quite certain are readily understood as expressing varying degrees of confidence, especially when they refer to a person. Phrases in which certain is modified can be quite effective, as the following example from Susan Orlean shows: "The [taxidermic] piece was precise and lovely, almost haunting, since the more you looked at it the more certain you were that the birds would just stop building their nest, spread their wings, and fly away." Note that since certain must always suggest overall confidence, its range is restricted to the upper range; one is less likely to be slightly, somewhat, or a little bit certain, for example.

certain

sure">sure1. having no doubts

If you are certain or sure about something, you have no doubts about it.

He felt certain that she would disapprove.I'm sure she's right.2. definite truths

If it is certain that something is true, it is definitely true. If it is certain that something will happen, it will definitely happen.

It is certain that he did not ask for the original of the portrait.It seemed certain that they would succeed.

Be Careful!
Don't say that it is 'sure' that something is true or will happen.

3. 'be certain to' and 'be sure to'

Instead of saying that it is certain that someone or something will do something, you can say that they are certain to do it or are sure to do it.
