Korean Grammar Point: (으)면 [(eu)myeon] (If, when)

1. Introduction

In Korean, the conditional and temporal clause marker (으)면 is widely used to express "if" or "when". It's an essential grammar point that allows speakers to discuss possibilities, conditions, and future events contingent on certain circumstances.

2. Core Grammar Explanation

Meaning

The suffix (으)면 is attached to verbs, adjectives, or nouns with the copular verb 이다 to form conditional statements. It conveys the meaning of "if" or "when", indicating that one action or state is contingent upon another.

Structure

The formation of (으)면 depends on whether the stem ends with a vowel or a consonant.

• For stems ending with a consonant (excluding 'ㄹ'):

  [Verb/Adjective stem] + **-으면**
  

• For stems ending with a vowel or the consonant 'ㄹ':

  [Verb/Adjective stem] + **-면**
  

Formation Diagram

Stem Ending	Attach	Example Verb/Adjective	Conjugation	Meaning
Consonant (excluding 'ㄹ')	-으면	먹다 (to eat)	먹으면	If [I] eat
Vowel or 'ㄹ'	-면	가다 (to go)	가면	If [I] go
		길다 (to be long)	길면	If it's long

Detailed Explanation

1. Identify the verb/adjective stem:
   • Remove -다 from the dictionary form.

     • 가다 → 가
2. Determine the ending:
   • If the stem ends with a consonant (excluding 'ㄹ'), add -으면.
   • If the stem ends with a vowel or the consonant 'ㄹ', add -면.

   • 먹 + 으면 = 먹으면 (If [I] eat)
   • 가 + 면 = 가면 (If [I] go)
