Origin of unrestrained

Explanation

You know how your uncle Marvin is always screaming at the television when his game shows are on? That’s because he’s being unrestrained. Anyone exhibiting uncontrolled emotion is unrestrained, meaning they don’t hold back. Unrestrained comes from the French restreinte, which means “hold back.” When something is restrained, that thing is confined in some way. Unrestrained means just the opposite. When you’re feeling unrestrained excitement, you might jump up and down, or call all your friends to tell them how you feel. The unrestrained crush you have on the guy in math class might lead you to cover your notebooks with his name written in bubble letters. It happens to the best of us.
