"Four boys are sleeping on this big brown bed."

Translation: Ezen a nagy barna ágyon négy fiú alszik.

[GerSzej]

why is: négy fiú ezen a nagy barna ágyon alszik, rejected? is it because the verb is at the end?

[pythagoras322]

sounds okay to me

[GerSzej]

thank you

[vvsey]

Yes, your sentence is OK, but it puts the emphasis on the bed. Which is fine, just not the neutral version. It could be accepted though.

[GerSzej]

Now that I have started learning the lessons on preverbs, where an explanation is given about words order, I understand much better this and other comments. It is actually very interesting. I learnt and speak Japanese, where words order is also very important.

Why is "négy fiu ezen a nagy bárna ágyon uszik" not accepted?

[Cauldie]

uszik?? (= swims); barna has 2 As, and no A's, but that's NOT why.
I say your version is good (if alszik, instead of uszik)

[Geoffrey.Lorenz]

Why is fiú in singular here?

[Cauldie]

because 4 boys. if you don't say how many objects, then it must be plural. if you say the number, that tells that it's plural. in Hungarian, the nouns remain singular with any number.

[Hrvoje981498]

It is because in Hungarian a noun is in singular if it is preceeded by any quantifier

[AlexandruC530730]

Too many pointless adjectives!!!

[Cauldie]

I understand practice, but they do sound unnatural & silly

[Cauldie]

sorry, but nobody sleep ON the bed in Hungarian (except pillows). People sleep IN the bed (ki aludt az agyamon? no, az agyamban!)
