I’m having trouble remembering different vocabulary with the same kanji that end in す or る, for example 写す and 写る. One is to copy and one is to be photographed. I have the same same problem with 上がる and 上げる, but the す and る ending seems to occure more often, so it’s becoming a nuisance.
Is there a rule that I am not seing? Is one something you do and one something you do to others or one is passive? Like a general rule that can be applied to all/most expressions like these? Everytime I think I got the hang of it a new one comes around that overthrows everything I thought I knew
