What does "You Hit the Nail on the Head" mean?
Hi, Aysi_Yilmaz.
"You hit the nail on the head" means that someone said or done something that is exactly right. It is the same as saying “you nailed it”.
We can say this idiom like this, “My mom hit the nail on the head when she guessed the exact amount of the bill we had to pay at the restaurant yesterday.”
In a conversation, you can say:
You: Mom, guess how much our bill is?
Mom: Hmmm, 151 and 30 euros?
You: Wow, you hit the nail on the head. (You nailed it!)
