What does speculum mean?
A speculum is an instrument that makes an otherwise inaccessible area visible. In modern medicine, it is inserted into a body cavity to hold tissue apart and allow a physician to inspect the interior, as with a vaginal or nasal speculum. Historically, the term also referred to a polished metal mirror, particularly one associated with ancient Roman religious, literary, or medical practice. The word can more generally describe an optical instrument used for viewing or directing light. Today, its best-known use is in physical examinations, where it has become a familiar part of gynecological and other diagnostic procedures. The term comes from Latin, where speculum meant a mirror or looking-glass. Its modern medical meaning developed as physicians adopted specialized instruments for examining internal parts of the body.

Where does speculum come from?
The English word comes from Latin speculum, meaning a mirror or looking-glass. The Latin noun was derived from specere, “to look,” the same root found in words such as speculate, inspect, and perspective. Latin specula also gave the language its word for the observatory commonly known as the Tower of the Winds in ancient Rome. In English, the medical sense developed through the use of instruments designed to expose and inspect internal parts of the body.
