Root Explanation

Acetabulum is derived from the Latin word 'acetabulum' (meaning little vinegar cup), which is a diminutive form of 'acetum' (meaning vinegar). The term originally referred to a small cup used for vinegar, and in anatomy, it describes the cup-shaped socket of the hip bone that holds the head of the femur.

Memory Tip

Imagine a small cup ('acetabulum') that holds something important, just like the acetabulum in the hip holds the femur.
