"When we are done, we rise up into the sky and become a star..." (Source)
I accidentally came across this website and bumped into "rise up". I would like to know if it's a superfluous usage or some usage I'm not aware of?
The idea of "up" is already contained in the verb "rise", which means moving something to a higher level and "rise" means "to move upwards; ascend". What difference is there between "rise up" and "rise"?
