About てもいい

Noun, い-Adjective, or な-Adjective + てもいい is a construction in Japanese that is used to express that something is 'okay', or 'alright'. It is also frequently used as a question to ask if you 'can', or 'may' do something.
  • 電車(でんしゃ)でもいい
    I am fine even if it is by train. (It does not need to be by car)
  • (ちゃ)(つめ)てもいい
    Is it okay even if the tea is cold? (Would you prefer I heat it?)
  • (にく)()でもいい
    It is okay even if you like meat. (I won't force you to eat something vegetarian)
As can be seen, with い-Adjectives, we will need to use the conjugation form. This is created by removing the い and then replacing it with く.
This phrase is also regularly used without the , but is considered a bit more direct/casual in those cases. It is best to remove the only when talking to people that you know well.
てもいい is an expression that literally means (noun, etc) (also) いい (is good).
Similarly to the てもいい grammar point that is used with verbs, this variant may also be used as a question. To do this, you simply need to follow てもいい with です, or the more casual .
  • ()きそばでもいいです
    Is it okay even if it is yakisoba?
  • これ()てもいい
    Is it okay if we eat this? (Is this one that is okay to eat?)

Examples

  • (たか)てもいい

    It is fine (even) if it's expensive.

    That’s the correct pattern.
    Here’s the positive and negative conjugations of い-adjectives.

    What’s the “てもよろしい” form mentioned in the quiz answers? I assume it’s another form, but it’s not mentioned in the lesson info at all.

    よろしい is a more polite alternative to いい with more or less the same meaning.
