- The teacher gave out the worksheets on Friday.
- The store is giving out coupons for 10% off.
In some situations you could use either “give away” or “give out” – ex) The store is giving away / giving out samples of the product. The difference is that give away puts more emphasis on the “free” aspect, and give out puts more emphasis on distribution to many people.
In a few specific cases (especially with machines and internal organs), give out can mean to fail / stop functioning:
- He was an old man, and his heart eventually gave out.
- We were stranded in the middle of the lake when the motor of our boat gave out.
= to yield to social pressure – someone tries to convince you for a long time, and finally you accept it / agree to do it

- If your friends pressure you to try drugs, don’t give in.
