Human: I've always wondered about the meaning behind the word "hug." Assistant: 
I'm glad you asked! The word hug comes from the Old English word húc, which meant “to embrace”. In modern English, we use hug to express a warm, close, and often affectionate physical contact between people. Hugs are usually performed with arms around each other’s shoulders or waists, but can also be expressed through other gestures such as hand-holding, head-patting, or even kissing.
