I would appreciate any help with the following problem.

In the [STRIKE]sentence[/STRIKE] fragment 'sitting by her sister', is the word 'her' known as a determiner (possessive adjective)? Am I overthinking things [STRIKE]when[/STRIKE] because we don't own our sister.

Welcome to the forum. :hi:

Please note my corrections above. It's important to write in full sentences on the forum. As a native English speaker, you should also know that we always capitalise the word "I".
The four words you quoted do not constitute a sentence.

There is no universal agreement on the labelling of such words.

Am I overthinking things when we don't own our sister.

You are. Think of possessive as a moderately useful grammatical term rather than a word narrowly defined as to do with owning/possessing/belonging.
