Usage tips
Word structure
The word consists of the prefix 'un-', which expresses negation, and 'beteiligt' (involved). 'Beteiligt' is the past participle of the verb 'sich beteiligen' (to participate / to get involved). So 'unbeteiligt' literally means 'not involved'.
EXAMPLE
Die Polizei befragte mehrere Personen, die am Streit unbeteiligt waren.
The police questioned several people who were uninvolved in the dispute.
Sentence structure with a preposition
To express what someone is not involved in, German uses the preposition 'an' followed by the dative. The structure is: 'an etwas (Dativ) unbeteiligt sein' (to be uninvolved in something).
EXAMPLE
Er schwor, dass er an dem Verbrechen völlig unbeteiligt war.
He swore that he was completely uninvolved in the crime.
Typical collocations
In the meaning 'gleichgültig' (indifferent), 'unbeteiligt' often describes a reaction or facial expression. Typical combinations are 'eine unbeteiligte Miene' (an indifferent expression), 'ein unbeteiligter Blick' (an indifferent look), or 'unbeteiligt zusehen' (to watch indifferently).
EXAMPLE
Während alle lachten, schaute er mit unbeteiligter Miene aus dem Fenster.
While everyone was laughing, he looked out the window with an indifferent expression.

unbeteiligt vs engagiert
committed / engaged
'engagiert' and 'unbeteiligt' both describe how strongly someone is inwardly or practically involved in something. 'engagiert' means that someone acts with interest and commitment. 'unbeteiligt', on the other hand, means that someone does not take part or shows no real interest. So the contrast is: active and interested versus outside of it or indifferent. If someone helps with a task and takes responsibility, 'engagiert' fits. If someone just stands by or seems emotionally cold, 'unbeteiligt' fits.
unbeteiligt
Am Bahnhof steht meine Mutter unbeteiligt daneben, während die anderen über die Reise diskutieren.
At the train station, my mother stands by indifferently while the others discuss the trip.
engagiert
Er ist in der Schule sehr engagiert, weil er den anderen für die Prüfung hilft.
He is very committed at school because he helps the others prepare for the exam.
