Diving into the river with 飛びこむ
Vocabulary Explanation: Words ending in 込む

Takeo and Sunakawa meet Yamato at the park. Yamato sees that Takeo is soaked. Sunakawa explains that they saved a child from drowning.
- 大和:
- 「え!?… 砂川
( くんはあんまり濡( れてないね」- “Huh?!... You're not that wet, Sunakawa.”
- 砂川
( : - 「オレは受
( け渡( ししただけだから」- “I just did the handoff, is all.”
- 「こいつは飛
( びこんだから」- “This guy dived right in.”
- “I just did the handoff, is all.”
Key Points
1飛( びこむ = “to dive or jump into”
- 飛
( ぶ means “jump” or “fly”. 込( む adds inward motion, so the compound describes Takeo entering the river in a jump. - Sunakawa omits the destination because the panel makes the river clear. If he named it, he would use に: 川
( に飛( びこむ. - The speaker gives no information about Takeo’s posture. Here, “dive” means entering the water in a jump.
2飛( びこんだ is the plain past form
- 飛
( びこむ is a godan verb ending in む, so its plain past changes む to んだ: 飛( びこむ → 飛( びこんだ.
3オレは…だけ and こいつは… contrast their roles
- Sunakawa uses は to set his role against Takeo’s: オレは… / こいつは….
- With だけ, Sunakawa limits his role to the handoff. Takeo entered the river.
- こいつ is a rough, casual way to say “this guy”. It suits Sunakawa’s familiar way of referring to Takeo.
4Sunakawa uses から for two reasons
- Sunakawa ends both remarks with から: he stayed drier because he handled the handoff, and Takeo got soaked because he jumped in.
- In English, we can omit the repeated “because”: “I just did the handoff, is all. This guy dived right in.”
5あんまり〜ない means “not very”
- Yamato’s あんまり濡
( れてない means “not very wet”. 濡( れてない is the spoken form of 濡( れていない. - Yamato uses final ね to ask Sunakawa to confirm what she sees.
