HOW TO USE –아/어지다 AND -게 되다

Understanding how to express change in Korean is crucial for achieving fluency.

In Korean, two primary grammatical structures convey change and gradual change: –아/어지다 and -게 되다. These structures help describe transformations in states, conditions, or circumstances over time.

CHANGE WITH -아/어지다

-아/어지다 is used with adjectives to indicate a change in state or condition. It translates to become or get in English.

PATTERN

Adjective + -아/어지다

Notes on the sentence structure:

  1. Attach -아지다 to adjectives ending in or ㅗ.
  2. Attach -어지다 to adjectives ending in other vowels.
  3. Attach -해지다 to adjectives derived from 하다 verbs.

GRADUAL CHANGE WITH -게 되다

-게 되다 is used with verbs to indicate that something happened gradually, often beyond the speaker’s control. It can translate as “came to be,” “ended up,” or “became.”

PATTERN

Verb stem + -게 되다

  1. Attach -게 되다 to the verb stem.
  2. If the verb is in the past tense, use -게 됐다 or -게 되었다.
  3. If the verb is in the future tense, use -게 될 것이다.
