Word Root of INCREDIBLE
The Latin word credere, meaning “to believe,” gives us the root cred. Words from the Latin credere have something to do with believing someone or something. Something credible is easy to believe, while something incredible is so out of the ordinary that it is difficult to believe. Giving credit to something someone says is believing that it is true.
