Root Explanation

Ravelin → The word originates from the French *ravelin*, which refers to a small fortification or outwork in a fort. It is derived from the verb *raveler*, meaning to unravel or to separate, indicating a structure that is distinct from the main fortification. The term reflects the idea of a defensive structure that is separate yet connected to the main fort.

Memory Tip

Imagine a small fort that is 'unraveled' or distinct from the main structure — that's what a ravelin is, a separate defensive work.
