Examples of ~た+ことがある

Alternate Explanations

Someone has done something. Someone has had an experience doing something. There was a time when ~.

In general, Sinf-past ことがある expresses the idea that there was a time when someone or something was in a state or did something.

More specifically, Sinf-past ことがある expresses one’s experience. In this case, Sinf-past ことがある is an extended use of the possession expression “Aは Bが ある”, where B is a past action rather than a possessed thing. This extended use of the possession expression of experience in Japanese is parallel to that in English. Possession: “I have a car.” Experience: “I have [studied Russian.] (past action)”

The た form of a verb, followed by ことがある, expresses experience: someone has had the experience of doing something or being somewhere.

To express a lack of experience doing something or being somewhere, こと が/は ない is used in place of こと が ある.
