Specifically, as noun words, "failing" means a weakness, usually in reference to a person's character. Whereas "failure" is a lack of success. Or "failure" can mean not doing a required or expected action or process. Ex: Every failure brings us closer to success! Ex: Our project was a complete failure. Ex: There was a failure in the operation system. Ex: Laziness is a failing of mine. Ex: Henry's failing is his anger.
