: -더니 Expressing Discoveries and Results

2. Grammar Explanation

: The expression -더니 is used in Korean to indicate a direct observation or experience in the past and how it led to a subsequent result or change. This grammatical structure allows the speaker to describe a cause-and-effect relationship they witnessed or experienced firsthand. The expression -더니만 is an extended form with a similar meaning. Key points to remember:

• The subject of both clauses must be the same.

• It cannot be used with the future tense.

• It is typically used with 2nd or 3rd person subjects, though it can occasionally be used with 1st person when the speaker objectively observes their own state.

• It highlights a natural progression from one state or action to another, often with an implied contrast or unexpected outcome.
