"Házat festesz?"

Translation: Are you painting a house?

[AlexandraV.]

Why is "Are you painting THE house?" wrong, if we didn't have either "egy" or "a" in the original sentence?

[RyagonIV]

Because a is required, but egy is not. If there's no article, it's "a house".

(Also "the house" would need a different conjugation: A házat fested.)

[AlexandraV.]

Thanks, this is very helpful!

[MrtonPolgr]

I personally feel no article is always a bit more indefinite than indefinite article itself.

How wrong or right would "egy házat festesz" be?

[krisz44g]

"Házat festesz", "Festesz egy házat", "Egy házat festesz" are all correct. Report it.

Is "Do you paint a house." correct or wrong?

[RyagonIV]

This is very correct.

[weitzhandler]

Reported.

Again, why isn't the simple present accepted here as well?

[cosmo-pedant]

Because it is a question . . .. Paint you a house? Well, okay: Do you paint a house?

[AnCatDubh]

I can’t recall. Is that painting as in applying paint or including in a two-dimensional work of art?

[RyagonIV]

It's about making a piece of art. As far as I know, it can be either making a painting of a house, or making a painting on the house. Applying paint simply to recolour it would rather be mázol.
