How to say "You are able to" or "You can do this"


Title says it all. I am looking for sentence structures that can convey this
meaning.




To say "you can/may ____" or "it's okay to ____", use this structure:

> [verb, te-form] + も (optional) + いい

This can also be used with negatives to say "it's okay not to ____"

**Positive Example: 「入っていいですよ」** (inviting someone to come into your
house/room)

**Positive Example (casual): 「入っていいよ」**

**Negative Example: 「心配しなくていいですよ」** "It's okay"/"Don't worry (about it)";
literally "it's okay not to worry"

**Negative Example (casual): 「心配しなくていいよ」**

Notes:

  * も, like a lot of other particles, is usually _ommitted_ when spoken or in chat and _included_ in formal, written communication like e-mail, letters, papers, books, etc.
  * The sentence ending ~よ is often tagged on the end of sentences that use this structure.
