It seems like both of these words can be transitive and mean “to make a mistake.”
So for the example sentence:
大事な事を間違うという経験を活かして、注意深い人間になるつもりです。
How would I know which word to use? Or would either be acceptable, and maybe Bunpro should warn me instead of marking it wrong?
Thanks!
I was also curious about this a while ago. I don’t know about bunpro, but from my understanding “machigau” used to basically be intransitive only while “machigaeru” was the transitive form. However, “machigau” was increasingly used as a transitive verb. I think that technically hardcore grammar purists would say using “machigau” transitively is incorrect, but it became commonly used and accepted.
