Questions & Answers about Ona już nie pracuje w biurze.
Together, już nie means no longer or not anymore.
- już by itself usually means already
- nie means not
But when they appear together before a verb, they often mean that something used to be true and is now no longer true.
So:
- Ona pracuje w biurze. = She works in an office / the office.
- Ona już nie pracuje w biurze. = She no longer works in an office / the office.
A very important contrast:
- już nie = no longer
- jeszcze nie = not yet
