stiff

The primary image is one of resistance to movement or flexibility, whether physical, emotional, or systemic. It suggests a lack of "give" or fluidity. Physically, it describes materials that resist bending or muscles locked in tension. Unlike "rigid," which can imply a permanent state, "stiff" often implies a temporary condition (like a stiff neck) or a quality that can be broken in over time (like leather). Socially, it carries a negative connotation of awkwardness and artificiality. A "stiff" person is someone who cannot relax, making them seem cold or robotic compared to someone "natural" or "easygoing." When applied to penalties or competition, it implies a harsh, uncompromising force. A "stiff breeze" or a "stiff penalty" suggests something that hits hard and resists easy mitigation.
