w korytarzu*

[Jellei]

Both should and do work here.

[Viezenz]

The associated pronunciation of the sentence ends with the inflection of a question.

[bnb525]

In? On?

[Jellei]

https://forum.wordreference.com/threads/in-the-corridor-or-on-the-corridor.2699648/ Seems that it really should be "in".

[Julia604611]

Would this also be the word for hallway/hall?

[Jellei]

Yes, both of those are accepted.

[margotgm]

why is it korytarzu rather than korytarz? how do nouns change with the locative case? is there some information about this somewhere?

[ZosiaD5]

Miejscownik zawsze występuje z przyimkiem w, we, na, o, po, przy.
The locative always appears with the preposition w, we, na, o, po, przy => so the noun korytarz (nom.) becomes korytarzu (loc.). Le locatif suit toujours les prépositions w, we, na, o, po przy. Donc le nom korytarz (couloir) devient korytarzu (dans le couloir)

[Christian7652]

Unfortunately not always,but very often
W piątek,na stację(direction),idę po chleb

[Will243093]

weird english. never heard of someone being "in" a corridor. my solution, "on" the corridor, rejected for a translation.

[alik1989]

I don't love it, but let's add 'on' anyway.

Btw, according to the iweb corpus being in the corridor is a lot more common than being on the corridor.
