-도록 · -게: So That / To the Point That

Once you know -(으)려고, you hit its wall fast: it can only express a goal you carry out yourself. But most real-world purposes are about someone or something else's outcome — "I wrote it big so that the students can read it," "be careful so you don't catch a cold." That is precisely the gap -도록 and -게 fill. They are Korean's "so that" endings for goals with a different subject, and -도록 has a bonus meaning -(으)려고 can't touch: "to the point that."

Forming them

Both attach to the plain verb or adjective stem — no vowel harmony, no -으- insertion:

• -도록: 늦다 → 늦지 않도록, 알다 → 알도록, 아프다 → 아프도록, 보이다 → 보이도록
• -게: 먹다 → 먹게, 자다 → 자게, 잘다 → 잘게, 보이다 → 보이게

Neither takes a linking vowel, and neither carries tense on its own clause — the time sits on the main verb.

Use 1: purpose "so that" — and the subjects can differ

This is the headline feature. Where -(으)려고 demands one shared subject, -도록/-게 freely let the two clauses have different subjects. The first clause states an outcome you want for someone/something else, and the main clause is what you do to bring it about.

Here the students see, but I write — two different subjects. -(으)려고 cannot express this (×학생들이 잘 보려고 크게 썼어요 wrongly says the students both intend to see and do the writing). -도록 handles it effortlessly.

The negative frame -지 않도록 ("so that … doesn't happen") is extremely high-frequency — it's the standard way to say "so as not to / so you don't."

Even when the subjects happen to be the same, -도록 can still work; it just leans toward a slightly more formal, deliberate "so as to" tone, common in instructions and writing.

-게: the everyday twin of -도록

-게 covers the same "so that / in such a way that" ground and is more colloquial. It often pairs with a resulting state, and like -도록 it allows a different subject.

In practice -게 and -도록 overlap heavily in the purpose sense; -게 sounds a touch lighter and more conversational, -도록 a touch more formal and emphatic. Both are correct.

Use 2 (only -도록): "to the point that / until"

Here -도록 does something -게 and -(으)려고 both lack. Instead of a purpose, it marks an extent — the main action is carried so far that it reaches the point described in the -도록 clause. English renders it "until" or "to the point that."

Notice the tell: the -도록 clause describes a degree or endpoint reached (throat hurting, all night, voice gone), not a goal you were aiming at. Nobody sings in order to hurt their throat — the throat pain marks how far the singing went. This extent reading is a favorite of native speakers for vivid, emphatic description, and it is worth practicing because English speakers routinely miss it, reaching for a plain "until" clause instead.

A note on -도록 하다 / -게 하다 (not this page)

Both endings also feed causatives: -도록 하다 and -게 하다 mean "make/see to it that someone does something" (늦지 않도록 하세요 "make sure you're not late"; 아이에게 채소를 먹게 했어요 "I made the child eat vegetables"). That's a distinct construction — the "so that" link swallowed into a causative predicate — and it's covered on -게 하다 (causative) and -게 만들다. On this page we stay with the pure "so that / to the point that" connective.

Common Mistakes

1. Using -(으)려고 for a different-subject goal. When the outcome belongs to someone else, -(으)려고 breaks; use -도록/-게.

2. Missing -도록's 'to the point that' reading. Don't force a purpose interpretation where an extent is meant.

3. Inserting a linking vowel -으-. Both endings attach straight to the stem.

4. Marking tense inside the -도록/-게 clause. The goal/extent clause stays tenseless; time lives on the main verb.

Key Takeaways

• -도록 / -게 = "so that," and unlike -(으)려고 they allow different subjects — the goal can be about someone/something else's outcome (학생들이 볼 수 있도록 크게 썼어요).
• The negative -지 않도록 ("so as not to") is a workhorse: 감기에 걸리지 않도록 조심하세요.
• -게 is the lighter, more colloquial twin; -도록 is a touch more formal/emphatic. In the purpose sense they overlap heavily.
• Only -도록 also means "to the point that / until" (목이 아프도록 노래했어요) — read the first clause as a reached endpoint, not a goal.
• Attach to the bare stem, no -으-, no tense; and don't confuse the pure connective with the causatives -게 하다 / -게 만들다.
