Etymology
Origin of optimist
First recorded in 1760–70; from French optimiste, from Latin optim(um) ( see optimum) + French -iste -ist
Explanation
An optimist is someone who always sees the bright side of any situation — a trait that can be either encouraging or annoying, depending on your frame of mind. Winston Churchill once said, “A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.” When you think about the problems in the world, it might sometimes be difficult to remain an optimist. Yet some people just naturally look for the silver lining, like Eeyore in the Winnie the Pooh stories who, when admitting that it's still snowing and freezing, remarks, "However, we haven't had an earthquake lately." Now that's an optimist!
