I was watching a "Chibi Maruko Chan" episode about Maruko wanting to pet a fluffy dog. In the subtitles, I saw「ずっと触ってたくなるよね」. So I understand that ずっと means "continuously," and that さわって is the te-form of 触る. What I don't understand is what たくなるよね means. At first, I thought that たくなる was たい (En: want) conjugated to たく when なる (En: become) is attached. However, たい is typically attached to the masu-stem of the verb, not the te-form. This is where the confusion arises.

  • On second thought, it could be that the caption writer made an error and that it really should be 「ずっと触っていたくなるよね」。In this case, たい would be attached to いる

  • I think it's possibly a reduced form of たくなる. Coming from a girl with -chan in her name....it's probably shorted to "takunaru" to make it cuter. xD Examples of this shortened form: ejje.weblio.jp/content/…

  • Just to clarify something: Did she say this after she stopped petting the dog?

    @NatsuKage Verbs conjugate to ~たい to express 'I want to ...', which conjugates like an い adjective, thus ~たくなる. ~したくなる is form specifically for する.

  • So Tama-chan(Maruko's friend) says this after Maruko describes how fluffy the dog is. Tama-chan would like to pet the dog continuously, it seems.

As you guessed in your comment, ~てたくなる is a form of ~ていたくなる. (I wouldn't call it an error, though. This is a very common colloquial pronunciation.) It is not a shortened form of したくなる, because したくなる cannot even fit in these sentences to begin with.

~ていたくなる is form of ~ていたい, which is itself a form of ~ている. As ~ていたい means 'want to ~ている', ~ていたくなる means 'become wanting to ~ている'. With your example, ずっと触っていたくなる would mean '[If I pet it], I'd want to be petting it for ever'.

  • Could you please give a good example of ~ていたくなる and a translation? Thank you!
