Is it necessary to use “oleh” here ?
why oleh is required here, and not in "kamu dipanggil ibu"
I thought that 'dipanggil' means is called when translated and do not understand why yang has to be inserted.
To make it simple, it's like saying "Who is that called by them?" = "Siapa yang dipanggil oleh mereka?"
Thank you demoksaputra. learning a new language is never so easy as people make it out to be.
