The Rule

ㅎ irregular color adjective. Same as 빨갛다: ㅎ drops + vowel merge. 하얗 + 아요 → 하얘요. 하얗다 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: 하얗 Polite present (해요체): 하얘요 Polite past: 하얬어요 Polite future: 하얄 거예요 Formal (합쇼체): 하얗습니다 Negative: 안 하얘요 Notice how the stem "하얗" changes in some forms. This is the ㅎ-irregular pattern in action.

Real Examples
