About たい

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 , or . The difference in nuance is that something marked with 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.

  • あなた(はん)(つく)たい
    As for you, I want to make dinner. (This can never mean 'I want you to make dinner for me', and is a fairly unnatural sentence)

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.

  • アカネ()たい
    Akane, do you want to go too? (Sounds more like a question than an invitation)

              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.

              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
