The Korean Vowel ㅏ (a): Sound, Strokes and Example Words

What you will be able to do after this lesson

• Pronounce ㅏ as an open [a] and tell it apart from English "cat" and "day".
• Write ㅏ in 2 strokes and place it to the right of a consonant, as in 가 and 나.
• Explain why a vowel written alone needs the silent ㅇ (아).
• Read six example words aloud: 아이, 가방, 나, 바다, 사과 and 아빠.
• Hear the difference between ㅏ and ㅓ in 사다 and 서다.

Before you start: no earlier lesson is needed. Time: about 20 minutes. Level: A0, complete beginner.

How Do You Pronounce the Korean Vowel ㅏ?

ㅏ is pronounced [a]: an open "ah" made with a wide jaw, as in English "father". Hold the sound steady for one beat, then stop. Korean ㅏ does not slide into another sound the way English "day" does. Listen to the vowel name 아 first.

Revised Romanization, the official Latin-letter system of South Korea, writes ㅏ as "a". That spelling is only a learning aid. The sound is the one you hear in the recording, not the English letter name "ay".

Mouth and Tongue Position for ㅏ

Three body cues make ㅏ easy to copy:

1. Jaw: open the mouth wide, about as if you were showing a doctor your throat.
2. Lips: keep them relaxed and unrounded. They do not push forward.
3. Tongue: let it lie low and flat, with the tip resting behind the lower teeth.

Phoneticians call ㅏ a low, unrounded vowel. "Low" means the tongue sits low in the mouth, which is why the jaw drops. Because the jaw drop is so large, ㅏ is the easiest Korean vowel to find by feel.

How Is ㅏ Different from English Vowels?

ㅏ is not the English vowel in "cat" or the diphthong in "day". Those two English sounds are made with a half-closed jaw or a gliding tongue. Korean ㅏ has a single, steady position.

English spelling also misleads. The letter "a" in English stands for at least five sounds, such as "cat", "father", "day", "about" and "all". Hangul gives ㅏ exactly one sound. That is a real advantage: once you know ㅏ, every syllable with ㅏ sounds the same vowel.

Korean ㅏ is also not the word "a" in "a cat". If you find yourself saying "uh" (as in "about"), open the jaw further. If you find yourself saying "ay", stop moving the tongue after the vowel starts.

Why Is ㅏ Drawn This Way?

ㅏ is drawn as a vertical line with a short stroke on its right because the 1446 Hangul designers built vowels from three symbols: a dot for heaven, a horizontal line for earth, and a vertical line for a standing person. The design appears in the Hunminjeongeum Haerye, the explanatory book that came with the original alphabet.

In ㅏ, the dot sits to the right of the standing line. In modern printing the dot became a short stroke. Mirror the dot to the left and you get ㅓ. Put it above a horizontal line and you get ㅗ. Put it below and you get ㅜ.

The designers also sorted vowels into groups. ㅏ and ㅗ are called bright vowels (양성 모음, yangseong moeum), and ㅓ, ㅜ and ㅡ are dark vowels (음성 모음, eumseong moeum). ㅣ is neutral (중성 모음, jungseong moeum). This idea is called vowel harmony (모음조화, moeumjohwa). You will meet it again when verbs take the endings 아요 or 어요. For example, 가다 (to go) becomes 가요 (goes, polite), because its vowel ㅏ is bright. This lesson only previews the idea; bright and dark vowels explains what it means.

How to Write ㅏ in 2 Strokes

Write ㅏ with two strokes, always in this order:

1. Draw the long vertical line from top to bottom.
2. Draw the short stroke to the right of it, starting at the line and moving right, at about the middle height.

The short stroke is much shorter than the vertical line, and it stays clear of the top and the bottom. A common beginner error is to write the short stroke at the very top, which makes ㅏ look like a flag. Keep it near the middle.

For all vowels side by side, see Korean vowel stroke order.

Where Does ㅏ Sit in a Syllable Block?

ㅏ sits to the right of its consonant, because it is a vertical vowel. In standard writing, Hangul letters are not written in a straight line. They are packed into square blocks, and each block is one syllable. The shape of the vowel decides where the consonant goes.

ㅏ follows the first row. In 가, ㄱ stands on the left and ㅏ on the right, with the long line of ㅏ setting the height of the block. The layout is taught in detail in vertical-vowel blocks.

Writing ㅏ Alone as 아

Written alone, ㅏ is spelled 아, with the silent consonant ㅇ in front of it. Every Korean syllable block needs a consonant in its first position. When a syllable starts with a vowel sound, Hangul fills that slot with ㅇ. At the start of a block ㅇ makes no sound at all.

So "ah" is written 아, never ㅏ by itself. Writing the bare vowel is only done in a chart or when naming the letter. Think of ㅇ as an empty chair that keeps the block's shape. The Korean name of the letter ㅏ is 아, the same syllable.

Worked Example: Reading 아이, 가방 and 바다

To read a Korean word, split each block into its letters, say each sound, then join them. Here are three words that use only ㅏ and simple consonants.

Word 1: 아이 (ai), "child". The first block is ㅇ + ㅏ = 아, so the silent ㅇ gives only the vowel [a]. The second block is ㅇ + ㅣ = 이, which is [i]. Together they sound like [아이], "ah-ee", said smoothly with no pause.

Word 2: 가방 (gabang), "bag". The first block is ㄱ + ㅏ = 가, which is [ga]. The second block is ㅂ + ㅏ + ㅇ = 방. Here ㅇ sits under the vowel as a final sound, and in that position it is the "ng" of English "song". The word sounds like [가방], "gah-bahng".

Word 3: 바다 (bada), "sea". Both blocks have a vertical vowel: ㅂ + ㅏ = 바 and ㄷ + ㅏ = 다. Each ㅏ is identical, so say [바다] as "bah-dah" with equal weight on both vowels.

Here are three more words with ㅏ, to say aloud after the recordings.

Notice the pattern in all six words: the vowel sound is the same wherever ㅏ appears. If you can say 아, you can say every one of them once you know the consonants.

The 가나다 Row: ㅏ with Every Consonant

The 가나다 row is the list of the 14 basic consonants each joined to ㅏ, in dictionary order: 가 나 다 라 마 바 사 아 자 차 카 타 파 하. Koreans call this ordering 가나다순 (ganada-sun, "ga-na-da order"), and it is how names are sorted in a Korean phone book. The word "ganada" is the Korean equivalent of "ABC".

The vowel never changes in this row. Only the consonant changes. That is why teachers start with ㅏ: you can learn all 14 consonants without worrying about a second vowel at the same time. The first consonant lessons start with the basic consonants, and every example there uses ㅏ.

How Can You Hear the Difference between ㅏ and ㅓ?

ㅏ and ㅓ differ by jaw opening and by the side of the stroke: ㅏ has the stroke on the right and a wider jaw, while ㅓ has it on the left and a slightly smaller jaw. The pair 사다 (sada, "to buy") and 서다 (seoda, "to stand") shows the contrast.

Use this memory cue for the strokes: the stroke points at the direction the vowel lives. In ㅏ the stroke points right, toward the rest of the syllable. In ㅓ it points left, back toward the consonant. It is only a hand-writing aid; your ears tell you the real difference.

A word-level test helps. Say 사다 slowly. Your jaw should open twice, wide each time. Then say 서다. The first vowel should feel smaller and further back. Because ㅏ and ㅓ are the pair most learners mix up, you will practise them again in the next lesson on ㅓ.

Which Mistakes Do Learners Make with ㅏ?

Learners most often make three mistakes with ㅏ, and each has a simple fix.

1. Writing ㅏ alone without ㅇ. Learners often assume the bare letter can start a word. Actually a Korean syllable block must have a first consonant slot, so "ah" is written 아. Fix: whenever you write a word that starts with a vowel sound, put ㅇ first.
2. Pronouncing ㅏ as the "a" in "cat". English speakers reach for [æ] because the letter looks like English "a". Actually ㅏ is lower and further back, so the mouth opens like a yawn. Fix: say "father" and keep only the first vowel.
3. Confusing ㅏ and ㅓ by stroke side. Learners often assume the stroke side is obvious, but in fast handwriting the short stroke drifts. Fix: check the direction against the consonant, then say the word aloud and listen for jaw width.

An expert tip: do not stretch ㅏ. The Standard Pronunciation Rules still separate long and short vowels, as in 말 [말ː] "speech" and 말 [말] "horse", but most present-day Seoul speakers no longer make that length contrast. Say ㅏ at normal length, crisp and calm.

Practice: Read and Hear ㅏ

Try each task before you check the answers.

1. Pick by ear. Play 사다 and 서다. Which one has the wider jaw?
2. Write. Write the vowel ㅏ alone as a full syllable, then write the block for [na].
3. Read. Read these words aloud and give the meaning: 아이, 가방, 바다.
4. Sort. Is ㅏ a vertical or a horizontal vowel? On which side of the consonant does it sit?

Answers to the Practice

1. 사다 has ㅏ and the wider jaw. 서다 has ㅓ and a slightly smaller opening.
2. 아 is the vowel alone; 나 is ㄴ + ㅏ, pronounced [na].
3. 아이 means child, 가방 means bag, and 바다 means sea.
4. ㅏ is a vertical vowel, so it sits to the right of the consonant.

If you missed an answer, replay the recording and say it with the clip. For extra drills, use Hangul flashcard decks, which play audio only when you tap, or test your ear with the Hangul quizzes. You can also build blocks yourself in the hangul syllable builder or explore every letter in the interactive hangul alphabet.

What Should You Learn after ㅏ?

Learn ㅓ next, because it is the vowel most often confused with ㅏ. You now know the Korean vowel ㅏ: its sound [a], its two strokes, its place to the right of a consonant, and its silent-ㅇ form 아. Continue with the lesson on the vowel ㅓ, which uses 사다 and 서다 again.

This lesson does not cover the sound of ㅏ inside longer words with final consonants, or how Koreans read ㅏ in fast speech. Those topics live in the syllable-block and pronunciation sections. If you want the overview first, return to basic Korean vowels, where all ten appear together, or see mouth diagrams on Korean vowel sounds. A full table of all 21 vowels is on the Korean vowels chart.

Honest limits of this page: mouth-position descriptions are approximations for English speakers, and the recordings are the real reference. The standard Seoul pronunciation is described; regional speech varies.

Frequently Asked Questions

Why is ㅏ written with ㅇ as 아? Every Korean syllable block needs a consonant in its first position. When a syllable begins with a vowel sound, the silent letter ㅇ fills that position and makes no sound. So the vowel ㅏ is written 아, and the same rule gives 어, 오, 우 and 이 for the other basic vowels.

Is ㅏ pronounced like the a in cat? No. The vowel in "cat" is a front vowel made with the tongue pushed forward, while ㅏ is a low central vowel with a steady, open jaw. The closest English match is the first vowel of "father". If your Korean ㅏ sounds like "cat", open the jaw wider and relax the lips.

How many strokes does ㅏ have? ㅏ has two strokes. First draw the long vertical line from top to bottom. Then draw the short stroke to the right of it, starting at the line and moving outward, near its middle. Stroke order matters in handwriting because it keeps blocks balanced and readable at speed.

What is the name of the vowel ㅏ? The name is 아 (a). Hangul Orthography, the National Institute of Korean Language rules, gives the vowel letters names that are the letter joined to silent ㅇ, so ㅏ is called 아, ㅓ is called 어, and ㅗ is called 오. Learners say the name when reading a chart aloud.

Which side does the short stroke of ㅏ go on? The short stroke of ㅏ goes on the right side of the vertical line. The mirror image, with the stroke on the left, is ㅓ. A quick check is to look at the consonant: the stroke of ㅏ points toward the rest of the block, while the stroke of ㅓ points back toward the consonant.
