Why Is It Called Lukewarm?

Have you ever heard the phrase “lukewarm” and wondered what it meant? It’s a common expression used to describe something as being neither too hot nor too cold.

But why is it called lukewarm? After all, what does Luke have to do with temperature? In this article, we’ll explore the history behind this word and why it’s come to describe things which are neither hot nor cold.

Why Is It Called Lukewarm?

The term ‘lukewarm’ is used to describe temperatures that are neither too hot nor too cold. Its exact meaning can vary between countries or groups of people, but it generally refers to a temperature that is slightly warmer than cool but still noticeably cooler than warm.

The origin of the term ‘lukewarm’ is not known with any certainty, but various theories have been put forward over the years.

Theory #1: Bible Origin

This explanation originates from the King James Bible, which refers to lukewarm water in one of its passages.

Specifically, it reads “I know thy works, that thou art neither cold nor hot: I would thou were cold or hot” (Revelation 3:15). This passage has been interpreted by some as referring to lukewarm water, but this is just speculation.

Theory #2: Temperance Movement

Another theory suggests that the term ‘lukewarm’ was first used in the 19th century, by followers of the Temperance Movement.

This was a movement that sought to limit or eliminate the consumption of alcohol in the United Kingdom. The term ‘lukewarm’ was used to describe individuals who were in favor of moderate alcohol consumption, as opposed to total abstention or extreme indulgence.

Theory #3: Drink Adjective

The third explanation is that the term ‘lukewarm’ was first used to describe drinks, especially alcoholic beverages. In particular, it is said to have been used to describe drinks that were served warm, but still retained some of their original chillness.


The exact origin of the term ‘lukewarm’ is not known for certain and there are several potential explanations for its origin.

Whatever its true origins may be, it has become a part of the English language and is used to refer to temperatures that are noticeably cooler than warm but not quite cold. Citations- https://www.
