Korean Grammar Point: ~혀/어/여 [hyeo/eo/yeo] (Because, so)

1. Introduction

In Korean, connecting clauses to express reasons or causes is essential for fluent communication. One common way to indicate cause and effect is by using the verb endings ~여/어/아 (-yeo/-eo/-a), which translate to "because" or "so" in English. This grammar point allows speakers to link two actions or states, where the first is the reason for the second.

2. Core Grammar Explanation

Meaning and Usage

The endings ~여/어/아 are attached to the verb stem to indicate that the preceding clause is the reason for the following clause.

• Usage: To express causation or reason between two clauses.
• Translation: "Because...", "So...", "Therefore..."

Structure and Formation

Formation Rules

Attach the appropriate ending to the verb stem based on the final vowel of the stem:

1. Verb stems ending with '아' or '오' vowel: Add -아 (-a)
2. Verb stems ending with other vowels: Add -어 (-eo)
3. Verb stems ending with '하다': Add -여 (-yeo), often contracted to -해 (-hae)

6. Common Mistakes and Tips

Error Analysis

1. Misapplication of vowel harmony:
   • Incorrect: 먹다 (to eat) → 먹아
   • Correct: 먹다 → 먹어 Tip: Since 먹다 doesn't end with '아' or '오,' use -어.
2. Overlooking contractions in 하다 verbs:
   • Incorrect: 공부하다 → 공부하여
   • Correct (contracted form): 공부하여 → 공부해 Tip: Remember that -하여 often contracts to -해 for smoother pronunciation.
