But water that has boiled into gas also gets a word: steam.

As far as I'm aware, there is no separate word for freezing water -- i.e. water that is very cold and will, if it continues to get colder (and has something to crystallise around), turn into ice.

So the symmetry seems complete: ice -> freezing water -> water -> boiling water -> steam.

Freezing water is already at or below 0, it doesn't need to get "colder" to turn into ice, it simply needs to exchange the energy with the environment and rearrange in crystals.

Basically as it gets colder water exchanges energy with the environment and gets colder.

But once it reaches freezing temperature, it can no longer get colder and all the energy is used for the formation of crystals.

		Yes, is that not the same with boiling water? It doesn't need to get "hotter" to turn to steam, it needs to exchange the energy with the environment to gasify

		So, I got the physics wrong. Apologies and thanks for the correction. But the semantic point still stands. Boiling water is still water -- in the specific sense of H2O in its liquid state -- while ice is not. The complaint that frozen water has a single-word synonym while boiling water does not is making a false equivalence.
