"A lány egy piros autó mellett áll."

Translation: The girl is standing next to a red car.

[BernardDe]

would The girl is standing "next to" a red car be right as well ?

[jzsuzsi]

That is also correct.

Note: when BernardDe asked this question, the main translation was "beside".

[HeruMornie]

What about "the girl stands by a red car"?

[DuckyNatalie]

thats what i put i am going to report it

[AmineHadji1]

I translated "... egy piros autó ..." by "... one red car" and got corrected. I thought since egy = one (the numeral), it could be used in this context. Is there a reason it's not possible here?

[HeruMornie]

See my other reply to your similar question about the building above a/one river.

In Hungarian the context defines clearly whether it is a numeral or an indefintie article. In this case the "egy" is the latter, so you must use "a".
(I am aware that sometimes English speakers use "one" as indefinite particle [like "you're one fine gentleman, sir"] but this is not a "proper" standard English.

[Chanah648069]

Not recognized as correct though

[Frank609231]

The girl stands next to red auto. There is a continuing inconsistency of acceptance of auto and car.

[HeruMornie]

I don't think that "auto" is a good English—I met either "car" or "automobile" only (or "ride" and such slang terms), but not "auto".

[RuT3oTh3]

I used "next to" and it was not accepted. Changes are needed
