「たい」の情報

たい is an auxiliary verb that is used to express things that you would like to do (want). To use たい, it needs to be added to the same conjugation base form of a verb that ます would be attached to.

When using たい, the thing that is 'wanted' can either be marked with を, or が. The difference in nuance is that something marked with が is considered to be wanted more. たい is conjugated in the same way as い-Adjectives, meaning that the negative, past, or past-negative forms may also be used.

たい is only used for expressing things that 'you' want, or repeating information/asking questions about what other people want. It may not be used to make guesses about what other people 'may' want, unless asking them directly.

Caution

たい is not used to tell other people that you want them to do something. This is done with ～てほしい.

Caution

たい is not usually used when giving invitations (asking someone if they want to do something with you). In these cases ～ませんか is far more natural.

    Structure

    • Verb[stem] + たい

    [たい belongs to a group of personal adjectives that can only be used to describe speaker’s/writer’s wishes/desires. If you want to describe someone’s wish/desire you have to use 「verb[stem]+たがる」 construction or indirect speech 「verb[stem]+たいと思う」]

    Object of desire can either take particle を or が.

    Can I ask a question about this?

    Okay, I’ve got that the grammar is Verb[stem] + たい
    So the stem of 答える is こたえ, and then you add たい.
    And I understand that you then need to put that in the past.
    What I don’t understand is how たい becomes たかった for the past.
    Is たい a verb? An adjective? And what rule is it following here?
    Any help much appreciated!

    Hey

    It is so called auxiliary (suffix attached to verbs) adjective. That is why it conjugates like one.

    Another example is verb[stem] + やすい

    In Japanese nomenclature, it is called 助動詞（じょどうし） - which is translated as “auxiliary verb”. But not all of those suffixes (たい for example ) conjugate like verbs so it might be misleading.

  • Marcus

    Marcus

    I see! Thank you so much!

    So the auxiliary adjective たい conjugates just like any い-adjective! Got it! Thank you so much!

    Yes, that is right!

    I think it would be helpful to have the past negative as a reference in the structure for this lesson.

    mrnoone

    Hey

    The past negative conjugation has been added

    Cheers,

    In the structure box, it is shown that the polite alternative for たくない is たくありません, but only for たくない.

    I know it sounds weird, but is this the same for たくなかった→たくありませんでした?

    Maybe even for these? (Honestly doubt it but who knows.)
    たかった→たくありました
    たい→たくあります.

  • mrnoone

    mrnoone

    @Pep95

    It simply conjugates like いadjective

    So:
    Polite non-past: たいです
    Polite past: たかったです
    Negative polite: たくないです/たくありません
    Negative polite past: たくなかったです/たくありませんでした

    are the allowed ones

    I hope it helps,
    Cheers

    I entered なりたい, and it wants me to type なら instead - but the audio is なりたい. Posting in the forum so I can provide a screenshot:

    And now, 2 hours later, I got it again, but this time it’s working correctly?

    I have informed the technical part of the team, the answers seem to be correct (なりたい)

    Hi, i’m sorry for asking a lot of questions, but I am really trying to understand how the grammar points are used.
    In this box is says that it should be used with を or が.
    But the examples never use が and even on the examples sentences page only a few use を.

  • IcyIceBear

    Don’t worry about asking questions that’s what these grammar point forums are for (⁠◠⁠ᴥ⁠◕⁠ʋ⁠)

    First, it doesn’t say that it should be used with を or が but rather able to use either. When marking an object of desire. So if the sentence doesn’t have that, then there’s nothing to mark. “I wanted to become a police officer” to become なる is always used with に, so no を or が in the なりたい sentences. For the 虫は食べたくない , the は is used for negative contrast instead. The sentence would still work with either を or が.

    プロの歌手と歌いたい, again no object of desire. “I want to sing with a pro singer.” If it was この歌(を/が)歌いたい you would use either marker, with が having more emphasis
