RIGID

There are certain things in life which are hard to change; it could be an idea ,a thought or even a habit. Rigid basically means something that is not flexible or just does not change. When you are unable to bend or move something, that means, it is rigid. For example, When your boss is very particular about the way the office functions and doesn't wish to change or bend the rules and regulations under any circumstances, that means he is a rigid man. 

Rigid also means something that is not flexible and is not going to change , no matter what happens. When you are stiff or unable to move because of a strong emotion such as anger or fear, it means you are rigid. As the word rigid describes something that is incapable of change, it is an adjective.
