The quality or state of being discomfortable; the degree to which something causes discomfort.
From discomfortable + -ness (noun-forming suffix from Old English -nes), stacking suffixes to create an abstract noun representing the quality of being discomfortable.
Stacking suffixes like dis- + comfort + -able + -ness shows how English builds complex meanings — each layer adds meaning, turning a simple feeling into a noun describing the quality of that feeling, which is why chemistry and philosophy texts love these multi-layered words.
