How to Conjugate 돕다 (to help): ㅂ-irregular Pattern

ㅂ irregular with ㅗ vowel: ㅂ → 우, then 오 + 우 + 아 → 와. 도와요.

The Rule

ㅂ irregular with ㅗ vowel: ㅂ → 우, then 오 + 우 + 아 → 와. 도와요. 돕다 follows the ㅂ-irregular irregular pattern. This means the verb stem changes when certain endings are added. Don't worry — once you learn this pattern, it applies to many other verbs too.

Why English Speakers Get It Wrong

English verb conjugation is relatively simple — "I eat, he eats, I ate." Korean is more complex because the verb ending changes based on politeness level, tense, AND the verb stem's final vowel or consonant. The ㅂ-irregular pattern is especially tricky because the stem itself changes. English irregular verbs (go→went) change unpredictably, but Korean irregular verbs follow learnable PATTERNS. Once you know the ㅂ-irregular rule, you can predict how all ㅂ-irregular verbs behave.

How It Works

Stem: 돕 Polite present (해요체): 도와요 Polite past: 도왔어요 Polite future: 도울 거예요 Formal (합쇼체): 돕습니다 Negative: 안 도와요 Notice how the stem "돕" changes in some forms. This is the ㅂ-irregular pattern in action.

Real Examples

• 도와요 (dowayo) — "help (polite present)" • 도왔어요 (dowateoyo) — "help (past)" • 도울 거예요 (dour geoyeyo) — "will help (future)" • 돕습니다 (dopseupnida) — "help (formal)" • 안 도와요 (an dowayo) — "don't help"

Common Mistakes

❌ 돕어요 (dopeoyo) ✅ 도와요 (dowayo) → ㅂ → 우, and 오+우+아 contracts all the way to 와. ❌ Using the casual form (돕어/아) in formal situations ✅ Use 돕습니다 when speaking to elders, at work, or in official settings → Mixing up politeness levels is one of the most noticeable mistakes foreigners make in Korean.

Quick Tip

Start by mastering the 해요체 (polite) form: 도와요. This is the form you'll use 90% of the time in daily life. Once it's automatic, add the past (도왔어요) and future (도울 거예요) to your toolkit.
