(으)면 = verb ending for “if”

<aside> 📎 Conjugation:

In order to add the meaning “if” to a verb, add -(으)면 [-(eu)-myeon] to the verb stem.

</aside>

1. Verb stems ending with a vowel + -면 Ex) 자다 [ja-da] --> 자면 [ja-myeon] (if you sleep)

2. Verb stems ending with ㄹ + -면 Ex) 길다 [gil-da] --> 길면 [gil-myeon] (if it is long)

3. Verb stems ending with consonants other than ㄹ + -으면 Ex) 작다 [jak-tta] --> 작으면 [ja-geu-myeon] (if it is small)

To make the sentence clearer, add the word 만약 in front of the verb or at the beginning of the phrase. Since most Korean sentences are heavily affected by verb endings toward the end of sentences, adding 만약 at the beginning makes it easier to understand that the sentence will be conditional.

Ex)

(1)Verb: 자다 = to sleep 지금 자면 [ji-geum] = if I sleep now 만약 지금 자면 = if I sleep now

(2)Verb: 비가 오다 [bi-ga o-da] = to rain

내일 밤에 비가 오면 [nae-il ba-me] = if it rains tomorrow night만약 내일 밤에 비가 오면 = if it rains tomorrow night

If what you are saying is simple and the sentence is not very long, you do not always have to use the word 만약 in each sentence.
