TO PAY SOMEBODY BACK

Hello again.

Today we continue with our money theme.

Today's expression is: to pay somebody back

It means: to return borrowed money.

Example 1:
Thanks for letting me borrow the 100 euros. I will pay you back as soon as I get paid. I promise!

Although this is not a difficult phrasal verb, I've included it because it's very common in conversation; much more common than 'return', and many people don't know it. Example 2 is also acceptable:

Example 2:
Thanks for letting me borrow the 100 euros. I will return it to you as soon as I get paid. I promise!

However, Example 1 is much more common in normal (informal) conversation.

Thank you very much for reading and have a great day!
