What describes something that is "tepid"?

The term "tepid" specifically refers to a temperature that is not hot or cold, but rather lukewarm. When applied to emotions or reactions, "tepid" conveys a sense of disinterest or lack of enthusiasm. Therefore, the choice that describes something as "lukewarm and unenthusiastic" perfectly captures the essence of the word. It conveys a moderate state, whether in terms of temperature or intensity, highlighting a lack of fervor or warmth in both physical and emotional contexts.
