The word "stiffness" derives from Old English stīf ("rigid, unbending"), likely from Proto-Germanic stīfaz, which also gave rise to Dutch stijf and German steif. The suffix -ness (Old English -nes) is a productive noun-forming element indicating a state or condition. The combination logically evolved from the literal sense of physical rigidity to metaphorical uses (e.g., social awkwardness).
