what are the Japanese, and English, technical terms for these verb transforms:
読める、買える、書ける、...
and this: 読まれる、買われる、書かれる、...
and this: 読ませる、買わせる、書かせる、...
Is there a standard term that textbooks use to call the changing of verb stems into those 3 different forms? "Verb conjugation" sounds natural, however "conjugate" does not sound correct in the context.
What do Japanese students call the changing of verbs into those 3 different forms?
thanks.
