"Το νερό είναι υγρό."

Translation: The water is liquid.

[Speugenia]

The EN sentence should not have the definitive article "the" IMO, as when discussing an element's physical properties in general (like here) one drops the definitive article to indicate the reference to the element in general -in contrast to the GR language that does the exact opposite in the same instance. So "Water is liquid" sounds more normal/proper EN I think.

I prefer "The water is liquid." because water in general can be a solid (ice), liquid water or a gas (steam). Thus, interpreting the sentence as discussing physical properties in general does not make sense. On the other hand, the sentence could be referring to a particular pot of water, hence: "The water is liquid." is quite realistic.

"Water is a liquid." sounds more natural.

[jeanprendiville]

Why not "water is a liquid" since there are other types of liquid? In the same way that "aluminium is a metal" is considered correct and "aluminium is metal" is marked incorrect.

What is not clear here for me is if υγρό is a noun (then a liquid as you said) or and adjective (is liquid and not solid). I know the second one could sound a little bit strange without a context.

Maybe if you add το is the noun and without it is the adjective...

[spdl79]

Yes, το υγρό is the noun for liquid.

The adjective is υγρός (m), υγρή (f) or υγρό (n) .

So υγρό can indeed be either an adjective or a noun, depending on the syntax.

When I saw this sentence I thought of the jocular truism "Water is wet"

[johndelaroo]

No, aluminium is always a metal, but water is a liquid only at room temperatures. It is solid below 0 degrees centigrade and a gas above 100 degrees centigrade.

[Bohuslav1]

But if water is above 100 or below 0 it isn't water anymore - it's steam or ice!

Aluminium will remain a metal until it reaches its melting point, which will then liquefy. It will also vaporise when it reaches its boiling point. This works the same way for every element

[risingape]

The point, however, is that aluminium remains a metal in each of these phases - it is a metal whether solid or not

[Annaphoric]

Aluminium will remain a solid metal until it reaches its melting point, which will then liquefy. It will also vaporise at its boiling point. This works the same way for every element

I noticed the same and was just about to comment :)
