The prefix pe- and the affix -an are used to form nouns
Penyerangan means attack
The root is serang (verb) which means to attack
I answered "Kapan penyerangan akan berakhir?" Which was accepted
Sorry... "... penyerangan ini..."
previous question marked kapan wrong. but here it is used in place of ketika
"Berhenti" instead of "selesai"?
