Usage
What are other ways to say certain?
Certain, one of a handful of adjectives indicating full belief and trust that something is true, suggests that there are definite reasons that have freed one from doubt. Confident emphasizes the strength of the belief or the certainty of expectation felt. Positive implies emphatic certainty, which may even become overconfidence or dogmatism. Sure, the simplest and most general term, expresses mere absence of doubt.
