What does "around" mean here?
The expression "this time around" is an idiom that means something has happened before and may happen again. "Around" here implies that the situation is circling around and happening multiple times. So adding "around" after "this time" implies that something is happening multiple times. Ex: She has been practicing and thinks she will do well this time around. Ex: We didn't do so well in the game last time around. Let's try harder this time around!
