A speculum is a medical tool used by doctors and nurses to examine parts of the body that are hard to see without help. It is usually made of metal or plastic, and it opens up a body part, like the vagina or the ear, so that the doctor or nurse can take a closer look inside. The word speculum is most commonly used in medical settings, but it can also be used in a more general sense to describe any tool that opens up and looks inside something.
