The Difference Between 出る (deru) Vs 出す (dasu)｜Japanese Grammar (N5–N3)

(Sun appearing [Deru] vs. Joy submitting homework [Dasu])

“The sun comes out.” (Hi ga deru) “I take out the trash.” (Gomi o dasu) They look similar, but 出る (Deru) is when something moves by itself, and 出す (Dasu) is when YOU move something. Let’s master this Intransitive/Transitive pair with Joy and Ken!

🗣 Conversation Scene

Joy is in the classroom with Ken.

Joy

先生（せんせい）に宿題（しゅくだい）を出（だ）しました。ケンさんは、もう教室（きょうしつ）を出（で）ますか？ (I “submitted” my homework to the teacher. Ken, are you “leaving” the classroom already?)

Ken

はい、出（で）ますよ。外（そと）は、もう月（つき）が出（で）ていますね。 (Yes, I am leaving. Look outside, the moon has already “come out/appeared”.)

🚧 Joy’s Mistake

(Trying to speak louder) ❌ Wrong: もっと声（こえ）が 出（で）て ください！ (Asking someone to “appear their voice” is strange.) ✅ Right: もっと声（こえ）を 出（だ）して ください！ (You want them to *produce/push out* their voice. Use Dasu!)
