I always mix up the above, any idea on how to separate the active / passive form?
出る - でる - to leave (passive)
出す - だす - to take out (active)
上げる - あげる - to lower something (active)
上がる - あがる - to fall (passive)
下げる - さげる - to raise (active)
下がる - さがる - to rise (passive)
with 下げる and 下がる, the “a” sound in が was my indicator for the passive action and the “e” in げ for the active word, but with 出す and 出る, it is just the other way round. Would love to hear from you how you remember vocabulary like these. Thank you so much in advance!
