Hey guys found some sort of pattern at least with the genki verbs, and I know some people have found patterns(but don’t always work) too I just wanted to add. I don’t feel like looking up if this applies all all verbs, or if someone mentioned this already so here we go
We can put them in to two categories, And three tiers of deduction:
All Verbs that end in す are transitive,
Transitive -----> Intransitive
壊す -----> 壊れる
汚す -----> 汚れる
落とす -----> 落ちる
沸かす -----> 沸く
Most Verbs That have the え in the middle, are transitive(unless they have a す counterpart)
Transitive -----> Intransitive
開ける -----> 開く
閉める -----> 閉まる
入れる -----> 入る
つける -----> つく
1st Tier of deduction:
If it has a す ending, it is always Transitive
2nd Tier of deduction:
If it has a く ending, its always Intransitive:
Transitive -----> Intransitive:
開ける -----> 開く
つける -----> つく
沸かす -----> 沸く
3rd Tier of deduction:
That leaves two verbs,
Transitive -----> Intransitive:
閉める -----> 閉まる
入れる -----> 入る
Which falls into the category of え middle being Transitive. (mostly)
Now at least you can pass your genki test in 15 minutes. :^)
Ah, didn’t realize you were referencing a specific page. I just thought of verbs that were in Genki. My bad.
The intransitive for 聞く would be 聞こえる.
As for 書く…It’s long past my usual bed time, so I’m drawing blanks. 書いてある would be the closest of which I could think immediately, but I don’t think it has a pair, actually. I’ll edit this tomorrow morning when I get a chance to get my brain working again and/or research.
I’ve found a good division on tran vs intran verbs. There’s always exceptions, but this might at least help learning those verbs that do have a pattern:
