Why do I need "adalah"?
Would "Jiwa mereka milikku" be wrong?
Wow duo where did you take my family?
Mwuahahahahhahaha!!! I am the all-evil-doing one!!!
But seriously... "Jiwa-jiwanya" means "Their" (plural possessive), doesn't it?
I mean, I get that -nya usually means one person and mereka should be used, but pluralising the noun should resolve that, no?
