So is Lagukan an actual word then? I lived in Malaysia for two years (as an LDS missionary), so I know about "lagu" and "-kan", but wasn't sure if the combination was actually correct or not.
The first thing I saw the name immediately relates to the Malay word Lagu. But no you don't see a word like this in real world, but you can certainly add them together.
in Indonesia no one actually uses it in day to day interaction but in some old text books or poetries they do use it
