Gratitude is a feeling of thankfulness and appreciation for something someone has done for you or for the good things you have in your life. It is the recognition of a positive impact someone's actions have made, and it often motivates people to reciprocate kindness or to express their appreciation in some way.
The word "gratitude" comes from the Latin word "gratitudo," which means "thankfulness." It is derived from "gratus," meaning "pleasing" or "thankful." The evolution of the word has maintained the core idea of being thankful for kindness or benefits received.
