nigeru-vs-dassousuru

Both 逃げる (nigeru) and 脱走する (dassou suru) can translate as “escape” or “run away” — but they are not interchangeable. 逃げる is the everyday word for running away from danger, responsibility, or a difficult situation. 脱走する carries a more dramatic, often military or institutional meaning: breaking out of a prison, fleeing a facility, going AWOL. Using the wrong one can sound strange or even comical. Here is how to tell them apart.

Yuka

Rei, I’ve seen 逃げる and 脱走する so many times but I always second-guess myself. Help!

Rei

Don’t worry — this is one of the most common points of confusion for English speakers. Let me clear it up once and for all!

At a Glance: 逃げる vs. 脱走する

逃げる — The Everyday Word for Running Away

逃げる is the go-to verb for fleeing, running away, or escaping in everyday situations. It covers a wide range of contexts: physically running from danger, emotionally avoiding a difficult conversation, or metaphorically escaping responsibility. It is one of the most versatile verbs in this semantic field.

The pattern is: [person/thing] + が/は + [place/person] + から + 逃げる.

Example 1 — physical danger:

火事が起きたので、建物から逃げた。
Kaji ga okita node, tatemono kara nigeta.
A fire broke out, so I ran out of the building.

Example 2 — avoiding responsibility:

問題から逃げてはいけない。
Mondai kara nigete wa ikenai.
You must not run away from your problems.

Example 3 — animal or criminal fleeing:

犯人は車で逃げた。
Han’nin wa kuruma de nigeta.
The suspect fled by car.

Yuka

Okay, that example with 逃げる really helped! I never saw it used that way before.

Rei

Right? Seeing real examples is so much more useful than memorizing a definition. 逃げる is definitely one of those words you’ll start noticing everywhere.

脱走する — Breaking Out of a Controlled Place

脱走する is much more specific. 脱 (datsu) means “escape/remove” and 走 (sou) means “run.” Together they suggest running out of a place of confinement. It is used primarily for prison breaks, military desertion, escaping from a hospital against doctor’s orders, or fleeing from a facility. It is more dramatic and carries a sense of breaking rules or boundaries.

You would not say 脱走する for simply running from a dog — that would sound absurdly dramatic. Reserve it for institutional or military contexts.

Example 1 — prison break:

囚人が刑務所から脱走した。
Shuujin ga keimusho kara dassou shita.
A prisoner broke out of jail.

Example 2 — military desertion:

兵士が部隊から脱走した。
Heishi ga butai kara dassou shita.
A soldier deserted from the unit.

Example 3 — humorous informal use (overdramatic):

退屈な会議から脱走したい。
Taikutsu na kaigi kara dassou shitai.
I want to escape from this boring meeting. (playful/humorous use)

Yuka

And 脱走する — is it used in formal situations, casual ones, or both?

Rei

Great observation! 脱走する actually works in both — context is everything. The comparison table coming up should make this super clear.
