How to clear a variable if "clear" is itself a variable?

I just started learning MATLAB Online and was assigning variables when I accidentally made "clear" as a variable. I have tried to clear the variables using several methods like "clear all", "clear clear", and "clearvars". But each is showing an error. How can I clear the variable?
