Root Explanation

Tetartohedral → It is formed from "tetarto-" (from Greek "tetartos", meaning fourth) and "hedra" (from Greek "hedra", meaning face or base). The word refers to a geometric figure that has four faces or is related to the fourth type of symmetry in crystallography.

Memory Tip

Think of 'fourth' ('tetarto-') and 'face' ('hedra') to remember that 'tetartohedral' relates to a shape with four faces.
