About たことがある

たことがある is a set expression in Japanese that is used for saying that 'there has been a time that I have done (A)'.

The auxiliary verb た will be added to the verb indicating what you have done, followed by こと - が - ある. Like の, こと is regularly used for nominalization (creating a noun-like phrase). However, の cannot replace こと in this particular grammar pattern.

From these examples, we can see that ない (the negative equivalent of ある) may also be used, when you want to express that you have 'never' done something.

Caution

Just like English, many set phrases cannot be adjusted in Japanese (in the same way that こと cannot be swapped with の in this expression).

Fun Fact

In expressions where こと is followed by a verb phrase, の may not be used. When used for nominalization, の is almost always followed by a noun or adjective phrase. Here are some examples.

  • 彼(かれ)は踊(おど)ることができる。
    He can do things like dance.
  • 来週(らいしゅう)は休(やす)みだから旅行(りょこう)へ行(い)くことにする。
    Because I have no work next week, I have decided to go traveling.
  • 今日(きょう)は帰(かえ)るのが遅(おそ)くなることになる。
    Today, I will end up coming home late.

        During my reviews, this sentence came up.
        ‘結婚けっこんしたことがありますか’

        Fair enough.
        But my answer of
        結婚けっこんをしたことがありますか

        This was rejected. Am I missing something? I thought you could use an を after a suru noun.

        Have I misunderstood something?

        mrnoone

        Hey Matt,
        I have added it as an alternative answer.
        The meaning is the same.

        The difference is that when you use するVerb + する you cannot modify (describe) the するverb with noun or adjective, with するVerbを + する you can.

        Example:
        数学の勉強する not natural
        数学の勉強をする natural

        幸せな結婚する not natural
        幸せな結婚をする natural

        But you can say:
        数学を勉強をする natural

        Cheers
