Root Explanation

Glacis comes from the French word 'glacis', which means a slope or incline, derived from 'glacer' (meaning to freeze or make cold). The term originally referred to a sloped bank or embankment, often used in military fortifications to provide a clear field of fire.

Memory Tip

Imagine a slope that is 'frozen' or 'cold' — that's what 'glacis' refers to, a sloped area often used in military contexts.
