"Yesterday I was not at the office."

Translation: Nie byłam wczoraj w biurze.

[skilja]

"Wczoraj mnie nie było w biurze" is wrong?

[Jellei]

Sounds fine I guess, added.

Should be also correct "Nie byłem w bierze wczoraj"?

[Emwue]

Sure, but it depends on gender of person speaking:

• male: „Nie byłem wczoraj w biurze”

• female: „Nie byłam wczoraj w biurze”

and also a possible form, but not actually used:

• neuter: „Nie byłom wczoraj w biurze”

[shadownavas]

Sure but my question goes about:
"Nie Byłem w bierze wczoraj"
"Nie byłem wczoraj w biurze"

Both should be correct isn't?

[immery]

"bierze" is "takes", "biurze" is office

word order is correct, even if less common

[Jellei]

OK, added. But that puts a surprisingly strong focus on 'yesterday'. Like in "I wasn't at the office yesterday, but on Sunday".
