### In the lessons

In science lessons about the skeleton it is often called a leftover of a tail from long-ago ancestors. In everyday life people hurt it when they fall on their bottom. Phrases: "bruise your coccyx", "tailbone".

### Examples

### Note

Pronounced "KOK-six". Plural: coccyges ("kok-SY-jeez") or coccyxes. It still has a job (holding muscles), so it is not completely useless.
