How to Conjugate 빨갛다 (to be red): ㅎ-irregular Pattern

ㅎ irregular: ㅎ drops and the vowel changes. 빨갛 + 아요 → 빨개요.

The Rule

ㅎ irregular: ㅎ drops and the vowel changes. 빨갛 + 아요 → 빨개요. 빨갛다 follows the ㅎ-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 ㅎ-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 ㅎ-irregular rule, you can predict how all ㅎ-irregular verbs behave.

How It Works

Stem: 빨갛 Polite present (해요체): 빨개요 Polite past: 빨갰어요 Polite future: 빨갈 거예요 Formal (합쇼체): 빨갛습니다 Negative: 안 빨개요 Notice how the stem "빨갛" changes in some forms. This is the ㅎ-irregular pattern in action.

Real Examples

• 빨개요 (ppargaeyo) — "be red (polite present)" • 빨갰어요 (ppargaeteoyo) — "be red (past)" • 빨갈 거예요 (ppargar geoyeyo) — "will be red (future)" • 빨갛습니다 (ppargahseupnida) — "be red (formal)" • 안 빨개요 (an ppargaeyo) — "don't be red"

Common Mistakes

❌ 빨갛아요 (ppargahayo) ✅ 빨개요 (ppargaeyo) → ㅎ drops and merges: 아 becomes ㅐ. ❌ Using the casual form (빨갛어/아) in formal situations ✅ Use 빨갛습니다 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: 빨개요. This is the form you'll use 90% of the time in daily life. Once it's automatic, add the past (빨갰어요) and future (빨갈 거예요) to your toolkit.
