〜たことがあります

## What it means This pattern talks about **life experience** — whether you've ever done something at some point, like 'I've been to Kyoto' or 'I've tried skiing.' It doesn't matter exactly when; it just says the experience happened at least once.

## When to use it Attach **ことがあります** to the **た-form** (plain past) of a verb. To say you've never done something, make it negative: **ことがありません**. To ask if someone has ever done something, add か: 富士山に登ったことがありますか。

## Don't confuse it with Don't confuse this with a plain た-form sentence like 行った ('I went'), which just reports a single past event. Adding ことがあります shifts the focus to 'this is something I have experienced,' even if it happened a long time ago or only once.
