Borrow or Lend?

So what's the difference between "borrowing" a book and "lending" a book?

"To borrow" means "to take something that belongs to someone else, and return it to them later." 

Examples:

• "Can I borrow your car?"
• "I need to return the book I borrowed from the library."
• "He borrowed 10,000 dollars from the bank."

Lend

"To lend" means "to give something to someone, when they need to return it to you later." 

Examples:

• "This library lends books for free."
• "The bank lent her a loan of 10,000 dollars."
  
  

In summary, borrowing is an action of taking, and lending is an action of giving.
