What does stiffening mean?
“Stiffening” is the noun form of “stiffen” and refers to the process of becoming rigid, resistant, or difficult to move.

Where does stiffening come from?
The word is formed from “stiffen,” which comes from the adjective “stiff” plus the suffix “-en,” meaning to make or become. “Stiff” itself derives from Old English, where it referred to rigidity, resistance, or severity. The noun “stiffening” developed through the same Germanic and Middle English word family, and its modern figurative senses reflect the longstanding comparison between physical rigidity and increased social or institutional tension.
