Ok, so the background is I have been struggling to differentiate intransitive and transitive verb in vocabulary review for the same kanji. So I tried to analyze my leech verbs and found out that there is some kind of pattern to help me differentiate intransitive and transitive verbs.
Up until level 10, these are patterns that I found and helping me a lot to not make mistakes in vocab review for the verb.
Rule 1: Ru (self, intransitive) and Su (object, transitive)
回る: to revolve - turn by itself (self, intransitive)
回す: to turn something. (another object, transitive)写る: To Be Photographed (self, intransitive)
写す: To Copy (another object, transitive)返る To be returned / to return (self, intransitive)
返す To return something (transitive)通る To Pass (self, intransitive)
通す To Let Pass (another object, transitive)Rule 2: Ma (self/intransitive) and Me (object, transitive)
決まる To Be Decided (self, intransitive)
決める To Decide (transitive)始まる To Begin (self, intransitive)
始める To Begin (transitive)止まる: to stop (self, intransitive)
止める: to stop something (transitive)Rule 3: Ku (self/intransitive) and Keru (object, transitive)
付く To Be Attached (intransitive)
付ける To Attach (transitive)開く To open / To be opened (intransitive)
開ける To open something (transitive)Rule 4: Any exception, need to manually remember for each
交じる To Be Mixed/to join (self, intransitive)
交ぜる To Mix (transitive)助かる To Be Helped (self, intransitive)
助ける To Help (transitive)化ける: to transform (self, intransitive)
化かす: to bewitch (transitive)etc…
The question is: am I going to the right path? since I can’t found anything on the web regarding this pattern until now. If there are any good references, would love to know.
Really appreciate it if anyone can give any feedback on this.
Thanks!
