2. Core Grammar Explanation

Meaning

~하여 is used to:

• Connect two clauses where the first clause is the cause or reason, and the second is the result or effect.
• Indicate that one action occurs after another in a sequence. It translates to "so", "therefore", "and then", or "by doing" in English.

Structure

Formation with -하다 Verbs

Most commonly used with verbs ending in -하다 (-hada).

[Verb Stem] + 하 + 여 → 하여

Example:

• 공부하다 (to study)
  • 공부하 + 여 → 공부하여

Formation with Other Verbs

While less common, ~여 can be attached to verb stems ending with vowels other than ㅏ or ㅗ.

[Verb Stem] + 여

Examples:

• 기다리다 (to wait)
  • 기다리 + 여 → 기다려
• 보이다 (to be seen)
  • 보이 + 여 → 보여 However, in modern Korean, these forms are often contracted (기다려, 보여) and ~하여 remains primarily associated with -하다 verbs in formal contexts.
