The prefix pe- and the affix -an are used to form nouns
Percakapan means conversation
The root is cakap (noun) which means talk (bicara is a synonym)

"I try AND remember our conversation" was marked wrong because of the AND. I believe you can't be too literal in your conversation in both Indonesian and the English Translation. "
"I try and ....... or I try to.........has exactly the same meaning.
