Thank you for your answers. Though now I wonder, why repeatedly embedding bridi into each other does not give the same semantic result as tanru or relative clauses do.
Why would something like 'lo lo lo gerku ku barda ku bunre ku batci ' not mean '[[[something is a dog] is big] is brown] bites'? Why does this not mean exactly the same as 'lo bunre barda bo gerku batci'?
