How to Say and Hear the Five Basic Korean Vowels: ㅏ ㅓ ㅗ ㅜ ㅡ
Learn to pronounce and tell apart Korean's five basic vowels ㅏ, ㅓ, ㅗ, ㅜ, ㅡ, with simple words and a quick listening contrast drill.
By TheaFirst conversations · Yapr Learn
Korean vowels are written as separate letters that combine with consonants into syllable blocks. This lesson teaches the five basic vowel letters ㅏ, ㅓ, ㅗ, ㅜ, ㅡ in isolation and inside simple words. You will learn what each letter sounds like, how to read it in Revised Romanization, and how to hear the difference between pairs that learners often confuse, especially ㅓ versus ㅗ. Korean does not have a simple five-vowel system like Spanish or Japanese, so treat these five as a starting set, not the whole inventory.
By the end, you can…
- pronounce the five basic vowel letters ㅏ, ㅓ, ㅗ, ㅜ, ㅡ in isolation.
- read and say simple Korean words that use these vowels.
- hear and distinguish similar vowel pairs such as ㅓ and ㅗ.
Listen once. Try it slowly. Then say it without looking.
Checking available voices…
ㅏ
the vowel a, as in 'father' but shorter
a, like the a in 'father' but shorter
Written with a short vertical stroke and a dot-like tick to the right. Appears in 아, the word for 'ah' and a common syllable in names.
ㅓ
the vowel eo, a mid back unrounded vowel
eo, like the u in 'strut' said with lips relaxed and unrounded
Do not round your lips. This is the vowel in 어, a common syllable meaning 'uh' or part of many words.
ㅗ
the vowel o, a rounded back vowel
o, like the o in 'go' but shorter and without the glide
Round your lips clearly. This is the vowel in 오, the Sino-Korean number five.
ㅜ
the vowel u, a rounded high back vowel
u, like the oo in 'moon' but shorter
Lips are rounded and pushed forward. This is the vowel in 우, meaning 'right' or 'above' in some contexts.
ㅡ
the vowel eu, a high central unrounded vowel
eu, like the u in 'put' but with lips spread wide and unrounded
Keep your lips flat and unrounded. This is the vowel in 그, meaning 'that' in 그 사람, 'that person'.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
Korean vowels are letters, not diacritics. A vowel can stand alone as a syllable, as in 아, 어, 오, 우, 으, or combine with a consonant: 나 (na, 'I'), 너 (neo, 'you'), 노 (no), 누 (nu), 느 (neu). The letter ㅇ at the start of a syllable is silent, so 아 sounds like 'a' and 오 sounds like 'o'. When you read a word, find the vowel letter first, then add the consonant sound before it. For example, 나 is n plus ㅏ, and 너 is n plus ㅓ.
When to use it
Use this vowel knowledge whenever you read a new Korean word. If you see ㅓ, keep your lips relaxed and unrounded; if you see ㅗ, round your lips. Compare 서 (seo) and 소 (so), or 커 (keo) and 코 (ko). In everyday speech, these differences change meaning, so practice them slowly before speeding up. Also remember that ㅡ is not the same as ㅜ: 그 (geu) and 구 (gu) are different words.
Listen to each line, then take one part and reply out loud.
이 모음은 뭐예요?
What is this vowel?i mo-eum-eun mwo-ye-yo?이건 ㅓ예요. '서'에 들어 있어요.
This is ㅓ. It is in 'seo'.i-geon eo-ye-yo. 'seo'-e deul-eo i-sseo-yo.그럼 ㅗ는요?
Then what about ㅗ?geu-reom o-neun-yo?ㅗ는 '소'에 들어 있어요. 입술을 둥글게 하세요.
ㅗ is in 'so'. Round your lips.o-neun 'so'-e deul-eo i-sseo-yo. ip-sul-eul dung-geul-ge ha-se-yo.A little context goes a long way
Korean vowel letters are taught in a fixed order in schools and textbooks, and learners often see ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ ㅜ ㅠ ㅡ ㅣ. The five vowels here are basic but not the only ones; Korean also has gliding vowels like ㅑ, ㅕ, ㅛ, ㅠ, and ㅢ. When speaking with Koreans, clear lip rounding and steady vowel quality matter more than perfect pitch, and Koreans will usually understand you from context even if one vowel is slightly off.
One thing to watch for
Pronouncing ㅓ like the English 'o' in 'go' and rounding the lips.
Try this instead: Keep your lips relaxed and unrounded for ㅓ. Say 서 (seo) with a neutral mouth, not 소 (so). If you round your lips, you may say a different word.
Your turn
Try answering out loud before checking a possible answer.
1Which vowel letter appears in the word 나 (na, 'I')?
Show a sample answer
ㅏ
나 is made of the consonant ㄴ plus the vowel ㅏ. The ㅏ sound is the 'a' in 'father', so 나 is pronounced na.
2How do you pronounce the vowel ㅡ in 그 (geu)?
Show a sample answer
With lips spread and unrounded, like the u in 'put' but without rounding.
ㅡ is a high central unrounded vowel. Keeping your lips flat distinguishes it from ㅜ in 구 (gu).
3What is the difference between 서 (seo) and 소 (so)?
Show a sample answer
서 uses ㅓ with relaxed, unrounded lips; 소 uses ㅗ with rounded lips.
The vowel letter changes the word. ㅓ is unrounded and ㅗ is rounded, so the mouth shape is the main cue.
Read Korean vowels as letters, not English spellings: ㅏ is a, ㅓ is eo with relaxed lips, ㅗ is o with rounded lips, ㅜ is u with rounded lips, and ㅡ is eu with spread lips. Practice the pairs 서/소 and 그/구 until the lip shape feels automatic.
