Other forms: optimists
An optimist is somebody who expects things to turn out well. The glass is half full, and probably refillable.
The word describes a disposition rather than a judgement about any particular case, which is why an optimist can be wrong repeatedly and remain one. Its opposite is a pessimist, and English has a well-worn joke about the realist standing between them. There is a philosophical origin in the argument that this is the best of all possible worlds, which Voltaire spent a whole novel demolishing.
