tepid

Imagine a cup of tea that's been sitting out for a while: not hot, not cold, just tepid. That's the literal meaning. But "tepid" also describes something that shows little enthusiasm. A tepid response to your amazing idea isn't very encouraging. It suggests someone is not strongly excited or interested. Think of a politician giving a tepid endorsement: they support the candidate, but without much energy.

The word comes from the Latin tepidus, meaning lukewarm, and originally referred only to temperature. Over time, it expanded to describe anything lacking intensity, whether in heat or feeling. If you're met with tepid applause after a performance, don't expect a standing ovation!

The word "tepid" primarily describes something that is lukewarm – neither hot nor cold. Think of bathwater that needs adjusting, or a cup of coffee left to sit for too long. "The water was tepid and unpleasant" might describe a disappointing swim. However, "tepid" has expanded beyond just temperature to describe a lack of enthusiasm, passion, or conviction.

A tepid reception means a lukewarm response – polite, perhaps, but not particularly enthusiastic. If your boss gives you a tepid "okay" on a new project proposal, it suggests they aren't thrilled, but won't outright reject it either. A tepid review, reaction, or endorsement often feels weak or uncertain rather than openly negative.

Historically, "tepid" was strictly about temperature, often used in formal or medical writing. Its figurative use is now very common and is frequently used to describe something that lacks energy or impact. A tepid argument isn't convincing, and a tepid defense of a friend feels half-hearted.

So whether you're talking about the temperature of water, the strength of an opinion, or the level of excitement surrounding an event, "tepid" signals something that is lukewarm, unenthusiastic, and lacking in intensity.
