Why is there a lukewarm but no lukecool?

Since I don't see it addressed yet:

“luke” derived from “lew” or “lewk” or “leuk”, in Middle English, which meant “tepid” (slightly warm). This in turn came from the Old English adverb “hlēowe”, which means “warm or sunny”. Finally, “hlēowe” came from the Proto-Germanic *hlēwaz, meaning “warm”.

The word “lukewarm” popped up around the 14th century as meaning “slightly warm”. Within two centuries, it also began having a figurative meaning, that of “lacking in enthusiasm”.

So lukewarm means "warm warm", except the repetition is basically the opposite of palilogia 🤣
- It's basically just East Timor/Timor-Leste, both meaning "east east".
  
  This time, instead of "east", it's "warm".
I always thought it came from that bible verse where Jesus says that if your faith is lukewarm he will spit you out of his mouth. I figured he was insulting Luke

Looks Luke cool to me.

I can eat 50 eggs.

Same reason there’s no Warm Hand Luke

Because it sounds like a porno title?
If my friend says he can eat 50 eggs...
- Are you friends with @Artyom@lemm.ee?

there is, tepid.

Isn't tepid = lukewarm?
- Depends what you were expecting. Cold coffee and warm soda are the same temperature.
I thought tepid was like neither warm or cool, so more of a lukemedium.
- if that's the case what's the difference between warm and hot i always thought lukewarm was the warm side and tepid was the cold side of medium. i don't think there true medium where you can't tell if it's warm or cool side.

Reminds me of Lost Positives by Rob Words. Disgruntled. what about gruntled?

Thanks for that link. Love discovering good educational channels.

Bcs Luke was never ever cool.

If you want to convey that something is cool af use Jean-Luc.

Because it doesn't looks cool

Lukewarm is French for moderately warm

I'd agree with the other response that tepid is the best word for this, but if you don't like that one you could use chilly, chill, brisk, or even just the word cool. The word cool implies on its own something that's just slightly cold.

But warm implies something slightly hot.

Hot → warm → lukewarm → room temperature
Cold → cool → ??? → room temperature
- I have a few observations
  
  Body temperature > room temperature. Lukewarm/tepid kinda occupies the space between. It is technically warmer than its surroundings, but does not provide a substantial warming effect to the body.
  
  Lukewarm is used almost exclusively for water, whereas room temperature is a reference to air temperature (either the current or a desirable one) Water and air exchange heat with the human body in different ways and at different rates. Room temperature air is fairly neutral to the body, but a 68F/20C swimming pool is rather chilly, and a 90F/32C room is not what I would call lukewarm.
  
  Warm & cool both have an implication of comfort whereas hot & cold have more an implication of danger or discomfort. Maybe there is something to thinking about these on more than one axis: relative temperature vs desirability or pleasantness.
  
  Context is weird. For things that are supposed to be “hot”, either “cool” or “cold could mean room temperature, above room temperature but also not quite “warm”, or hotter than “warm” but below a target, expected, or usable temperature.
- Tepid

I sometimes call water lookcool. To me its the really good drinking temp.

Because cool is pretty much the equivalent of lukewarm word for cold

hot warm lukewarm

cold cool ???

Cool isn't the lukewarm word for cold, cool is the warm word for cold.
- Oh well, then I'll invent the word lukecool and now everything is okay.

hot	warm	lukewarm
cold	cool	???

Our reference is warmth. Thermometers measure the activity of atoms which is proportional to temperature.
