I know that these sentences are right:

  • Where is it?
  • How are you?
  • How big is it?
  • Where are you from?

But I am confused about these sentences... so I want you to tell me which one is right. If the other one is wrong, please let me know the reason.

    • I know the place where is good.
    • I know where is a good place.
    • I know where a good place is.

    • I know the person who is kind.
    • I know who is kind.

    • I know when is the best time for you.
    • I know when the best time for you.

    • When is good for you?
    • When is the best time for you?

    • Where is good for you?
    • Where is the best place for you?

    • I don't know which is good.
    • I don't know which place is good.

    • Who is kind?
    • Who is better?
    • What is good for you?

    Please learn to use capital letters at the beginning of sentences. Also, the first-person singular pronoun is I not i (i.e. capital letter). – virolino Mar 4 at 9:30
  1. "I know a good place".

  1. "I know a/the kind person".

  1. "I know the best time for you".

  1. Both are correct!

  1. Both are correct!

  1. "I don't know which is better". Or, "I don't know which place is best".

  1. Without context, determining what you mean is impossible.

Note that these questions are all very short and ambiguous. Depending on the specific scenario, the questions could vary by a lot.

  • I mean... I am learning grammaer of "relative pronounce" .so.. i am not looking for the best sentence to say in each situation. I want to know if each sentence is possible or not. If it is right to say or write, I also want to know how it sounds like... "formal" or "informal" or "we can use it in written English like this... – Sunny Mar 5 at 0:39
