Rigid

Stiff and hard, so it can't bend or change easily, like a straight piece of metal or a strict rule that doesn’t allow for any differences.

Examples

• The table was so rigid that I couldn’t push it even an inch when I tried to move it.
• My teacher explained that some rules are rigid, meaning they can't be changed no matter what.
• The frozen pond looked beautiful, but I knew it was too rigid to walk on safely.
