How to Use It
Use ことがある after the past short form of a verb to describe a personal experience—something that has happened at least once in your life.
This grammar point can be used to both ask and answer questions about past experiences. In formal situations, you’ll use the full expression, while in casual conversation, it’s common to shorten the form and even drop the particle が. To express that you have not experienced something, conjugate ある into the negative. You can also use this grammar freely to talk about your own experiences, even when no one has asked you a question.
