calefringe
noun
A paradoxical sensation where touching extremely hot water evokes a feeling that is unexpectedly cooler than colder water, illustrating how intensity can sometimes mask or alter what we perceive as reality.
From Latin 'calefacere' (to warm, to heat) + Old English 'frignan' (to ask, to question), implying a questioning warmth. Pronounced "KAH-leh-frinj"
