Tepidly → It is formed from "tepid" (from Latin *tepidus*, meaning lukewarm) and the suffix "-ly" (meaning in a manner of). The word "tepidly" means in a lukewarm manner or with little enthusiasm.
Think of something that is 'lukewarm' ('tepid') and how it is done 'in a manner of' ('-ly'). This helps you remember that tepidly means doing something in a lukewarm or indifferent way.
