In Korean, the grammar point ~이어서 is a connective ending used to link clauses, indicating a sequence of actions or reasons. It is similar to saying "and then" or "because it is" in English. Understanding how to use ~이어서 can enhance your ability to create complex sentences and express cause-and-effect relationships.
2. Core Grammar Explanation
Meaning
The ending ~이어서 attaches to nouns ending with a consonant and means:
- "And then"
- "So"
- "Because it is..." It connects two clauses by indicating that the second clause follows as a result or continuation of the first.
Structure
- Noun (ending with consonant) + 이어서
- Noun (ending with vowel) + 여서

Detailed Explanation
