Why heart named heart?

The word "heart" comes from the Old English word "heort", which is related to the German word "Herz" and the Dutch word "hart". The word "heort" originally referred to the physical organ that pumps blood, but it also had a wider meaning that included the mind, the emotions, and the soul. The heart was thought to be the seat of intelligence and courage, and it was also associated with love and compassion. Over time, the meaning of the word "heart" narrowed to refer specifically to the physical organ, but the word's richer, more expansive meaning is still retained in many expressions, such as "to have a change of heart" or "to take something to heart."
