Warm or hot; possessing heat or warmth.
From Latin calidus meaning 'warm' or 'hot,' which is related to calor (heat). This adjective was used in Middle English and early modern English but is now largely archaic or technical.
This Latin root calidus gave us 'cauldron' and even influenced the word 'scald'—tracking the evolution of one word through centuries shows how heat-related vocabulary spread across European languages like warmth itself.
