"Rigid" refers to something that is stiff and inflexible, unable to bend or change shape easily. This term can apply to physical objects, like a metal rod, which does not easily flex under pressure, or to concepts, such as rules or beliefs that are strictly adhered to without consideration for exceptions. In a broader context, rigidity can also describe a person's mindset. Someone who is rigid in their thinking may resist new ideas or perspectives, preferring to stick to established ways. This can hinder creativity and adaptability in various situations, whether in workplaces or personal relationships.
