Translation: They are at school.

[spenerish]

Can this also mean "they are in the school"?

[SeanYu9]

Is ada necessary here?

[AVAX3M]

No.

[bambiewitch]

It seems logical for it to translate to "they are in the school" as well. Is this correct too?

[Sultan394734]

They are in school

[Sultan394734]

Mm

[sumsel1]

at school sounds about right to me. perhaps AE/BE issue?

"They are at the school" should also be accepted.
