lukewarm

lukewarm: [14] Lukewarm is a compound adjective based on the now obsolete Middle English luke ‘tepid’. It is not altogether clear where this came from, but it is generally assumed to be a derivative of the also now obsolete lew ‘(fairly) warm’, with perhaps a diminutive suffix. Lew goes back to an Old English hlēow ‘warm’, a variant of which became modern English lee ‘shelter’. It is related to Latin calor ‘heat’ (source of English calorie), calidus ‘hot’ (source of English caudle, cauldron, and chowder), and calēre ‘be hot’ (source of English nonchalant).
=> calorie, cauldron, chowder, lee, nonchalant
