1. Piles: In this context, "piles" refers to a condition known as hemorrhoids, which are swollen and inflamed blood vessels in the anus or rectum. The word "piles" originated from the Latin word "pila", meaning a ball, which was later associated with hemorrhoidal swellings due to their round appearance.
2. Out: "Out" is a preposition indicating movement away from a particular place or a state of being not concealed. Its etymology can be traced back to Old English where its original form was "ūt", which eventually evolved into the modern English word "out".
