Yeah, if "boiling water" is one word, what about boiling sugar? Boiling milk? Boiling volcano? Boiling soup?

Adding two words together creates a new and different concept. The permutations necessary to represent every concept ever formed by combining two or more different words would be endless.

Some of them on the list, like black hole, do make sense. That's a very distinct thing. It's not a hole in the conventional sense and it's not really black. Boiling water, though, is water. And it's boiling.

> to me

Your "to me" is actually problematic, because it legitimizes this nonsensical idea and turns words and their meaning into something purely individualistic, which cannot end well for the current, but even more so for the next generation.

I can confirm that "boiling water" definitively is "water that's boiling" and that two words, which are supposedly one word, definitely are not one word.

Boiling water is mostly same as boiling anything. So I would just have "boiling". No need for "boiling water". I see no reason why boiling water could not just be covered by whatever general boiling entry covers.

Some other words that are sorely missing from dictionaries: "Warm water", "hot water", "cold water", "dirty water"

Yep, all of the following make perfect sense to me, they're just non-idiomatic:

- Don't put your hand in water that's boiling,

- Add the pasta to water that's boiling,

- That saucepan is full of water that's boiling.

If "boiling water" were a distinct word, all of these sentences would change meaning compare to their idiomatic counterparts.

I’m so glad I’m not going insane. I don’t see any examples on that site that I agree are ‘one word’. Sure they’re singular concepts but so what? Are we going to have singular words to describe all adjective noun pairs now?
