What's correct?

[Gość: kk]

Once I've heard that it's not correct to say "I went to her". It should be "I
went to her's" instead.

Is it the same with nouns then? What's correct: "I went to my boyfriend's"
or "I went to my boyfriend"?

[mikajanka]

Mogę się mylić, ale wydaje mi się, że poprawne jest zdanie "I went to my
boyfriend". W przypadku tego pierwszego zdania, po boyfriend's powinno jeszcze
coś być np. I went to my boyfriend's house.
Ale to temat do dyskusji i fajnie by było, gdyby zabrała głos jakas mądra głowa.

"I went to her's" - what is that "her's"? Home, show, heart?

[Gość: kk]

home

Then it should be "went to her home". Or: "I went to see (visit) her".

I went to my boyfriend's

...is acceptable and qiute frequently used.
It contains implied (house, flat etc.).
This type of construct can be found in Pro Bono (Pro publico bono) and "Status
Quo (Est)".
Her's does not exist.

Jaki badz Noun albo Pronoun, jesli jest skonczony w 's to oznacza posiadlosc.
"I went to her's" prawidlowo to nieskonczone zdanie, ale na ulicy anglofonow
to sie spotyka bo nie zawsze mowia prawidlowo, wyjatkowie bez wiedzy ale czesto
na umyslnie do efektu ( przesada ).
