The prefix pe- and the affix -an are used to form nouns
Persahabatan means friendship
The root is sahabat (noun) which means friend (teman is a synonym)
Adrian thank you for taking part and helping us
Dinas and Tini
I can only hear "ini", not "Tini".
Another disastrous sentence. This pe-an section is poorly written
More natural english would probably be "how is dimas' friendship with tini?"
"Dimas's" is not a typo.
