Question

why we use the word thanks

Answer 1

"Thank you" is important because we are primates, and primates are inherently social creatures. When goods or services are exchanged, and currency is not involved, then our words and expressions must become the currency. "Please" is the socially acceptable word that signals a request for some sort of transaction to take place. "Thank you" is payment for services provided. "You're welcome" is a sales receipt. These exchanges are vital to our societal structure. At first glance, it may seem like a waste of time, but it's an important element to how we connect and bond with each other. Those two little words hold a tremendous value that most of the time we take for granted.
