About Verb + てもいい

Verb + てもいい is a construction in Japanese used to express that something is 'okay', or 'alright'. It can also be used as a question to ask if you 'can', or 'may' do something.

This phrase is also regularly used without the , but is considered a bit more direct/casual. It is best to remove the only when talking to people that you know well.

This expression is simply a construction that literally means (verb) (also) いい (is good).

Caution

As this grammar point uses the form of verbs, it is important to remember that some verbs will use instead of .

Examples

    Instead of 朝ごはんをつくってもいいです I incorrectly used 朝ごはんをつくてもいいです.

    Does someone have a link to a page with that table of conversions to the te-form verbs?

    In 質問を してもいい ? this is automatically a question, and the か marker is rejected. Is it the question mark that makes this a question?

    The sentence-ending particle か behaves as a question mark, so it should usually be one or the other. 「~ですか?」 looks unusual.
    In casual speech, I never use か, I just use an upward inflection (i.e. a question mark)

    Thanks, Matt.

    明日学校がにいってもいいです

    Should there not be some kind of particle between 明日 and 学校?


    Edit: Nevermind, found this:

    Note: Relative time expressions such as 今日 and 明日 do not take a particle.

    Why does it state in the notes that: む・ ぶ → で, when む・ ぶ・ ぬ should become んで?

    When I look at the alternate grammar I see this:

    もよろしい

    Which is not covered in the meaning section. Could you add some reference to it?

    I came across this similar grammar:
    権利: ある物事をしてよい、またはしないでよいという資格。
    Is it simply a more formal/literal version of てもいい?

  • mrnoone

    mrnoone

    @mrthuvi
    Hey

    You are correct. よい is the original pronunciation of いい (you can think いい as informal, similar to English “I am” and “I’m” difference), so definitely, it feels more formal.

    I hope it helps,
    Cheers

    By the way, the も in てもいい construction has “inclusive” function, that is it includes both cases, even if you do something, or even if you don’t do something it is (still) OK. So it is more indirect, leaving the person choice whether they will do something or not. In other words, it is up to the speaker.

    When there is no も it is more direct, basically “one is allowed to”.
    There is no alternative to “not do something” included.

    Though, this is not always the case, for example in casual speech も can be omitted without any special thinking behind it.

    I’ve heard that in this grammar point the “も” is not required. If true, It would be nice to indicate as such in the grammar description and to add a few exemple sentences without も. What do you think?

    Same for grammar point 46.

    @shary
    Added the note about the も particle
    And もless answers are accepted as alternatives.

    The first example is:
    これを見てもいい?
    Which it says means “is it alright if I look at this?”. However, because the subject isn’t stated, could it also mean “can you look at this?” (as in asking for feedback on something or showing something off), or would that be strange?
