Lesson 3 · Eleven additional vowel letters
Your goal: Complete the modern 21-vowel inventory and build blocks with each additional vowel.
Before you start: Know the 10 basic vowels and initial ㅇ. Familiarity with Lesson 2 helps you review the complete alphabet, but no tense-consonant sound assessment is required here.
Look → build → cover → try again. This is written practice, not a listening test. Answers are not saved.
A bigger vowel still fits one block.
Today: Build 와. Keep the vowel around the starting consonant.
1. Look at the parts
The parts form one vowel letter.
2. Add the starting position
Initial ㅇ adds no consonant sound.
3. Keep it together
One syllable block, not 오아.
Tap your answer
Choose the block made by ㄱ + ㅘ.
Try first. Then read the explanation.
Try now: combine ㄱ + ㅘ.
Check your answer
과. ㄱ is the starting consonant and ㅘ occupies one vowel position.
Now use the activities below. Start with one small set; return for the rest.
Small session 1
Four right-side vowels
The 10 basic vowel letters plus these 11 additional written vowel letters make 21. “Additional letters” is a spelling grouping—not a claim that all 11 are diphthongs. This first group stays to the right of its consonant.
ㅐ ae · example 애
Explore this letter: shape, build and practice
ㅏ with another upright line on its right.
Name / vowel example: 애 (ae). Position: To the right of the starting consonant.
Keep the spelling distinct from ㅔ, even when a speaker sounds similar.
Build: ㅇ + ㅐ → 애. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅒ yae · example 얘
Explore this letter: shape, build and practice
ㅑ with another upright line on its right.
Name / vowel example: 얘 (yae). Position: To the right of the starting consonant.
The y-glide partner of ㅐ.
Build: ㅇ + ㅒ → 얘. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅔ e · example 에
Explore this letter: shape, build and practice
ㅓ with another upright line on its right.
Name / vowel example: 에 (e). Position: To the right of the starting consonant.
Keep this spelling distinct from ㅐ.
Build: ㅇ + ㅔ → 에. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅖ ye · example 예
Explore this letter: shape, build and practice
ㅕ with another upright line on its right.
Name / vowel example: 예 (ye). Position: To the right of the starting consonant.
The y-glide partner of ㅔ in this basic example.
Build: ㅇ + ㅖ → 예. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
Try first: Which has two short arms pointing right: ㅐ or ㅒ? Build it with initial ㅇ.
Check your answer and why
ㅒ; ㅇ + ㅒ → 얘 (yae). ㅐ gives 애 (ae). Sound similarities do not erase spelling differences.
Small session 2
Three combinations built from ㅗ
Leave room below and to the right of the starting consonant. Components help you recognize the single vowel slot; do not read the component names as two syllables.
ㅘ wa · example 와
Explore this letter: shape, build and practice
ㅗ below-left joins ㅏ on the right.
Name / vowel example: 와 (wa). Position: Below and to the right of the starting consonant.
One vowel slot and one syllable, not two syllables.
Build: ㅇ + ㅘ → 와. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅙ wae · example 왜
Explore this letter: shape, build and practice
ㅗ below-left joins ㅐ on the right.
Name / vowel example: 왜 (wae). Position: Below and to the right of the starting consonant.
Watch for the extra upright line: ㅘ and ㅙ are different spellings.
Build: ㅇ + ㅙ → 왜. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅚ oe · example 외
Explore this letter: shape, build and practice
ㅗ below-left joins ㅣ on the right.
Name / vowel example: 외 (oe). Position: Below and to the right of the starting consonant.
Oe is Romanization, not instructions to say o then e. Standard pronunciation allows a diphthong too.
Build: ㅇ + ㅚ → 외. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
Try first: Build ㄱ + ㅘ, then replace only the vowel with ㅙ.
Check your answer and why
과 (gwa) → 괘 (gwae). Both have one block; the extra upright line changes the vowel spelling. These are construction examples, not a vocabulary test.
Small session 3
Four more wrapping vowels
ㅝ wo · example 워
Explore this letter: shape, build and practice
ㅜ below-left joins ㅓ on the right.
Name / vowel example: 워 (wo). Position: Below and to the right of the starting consonant.
The Romanization is wo, not weo.
Build: ㅇ + ㅝ → 워. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅞ we · example 웨
Explore this letter: shape, build and practice
ㅜ below-left joins ㅔ on the right.
Name / vowel example: 웨 (we). Position: Below and to the right of the starting consonant.
Compare the written components with ㅙ and ㅚ; do not merge their spellings.
Build: ㅇ + ㅞ → 웨. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅟ wi · example 위
Explore this letter: shape, build and practice
ㅜ below-left joins ㅣ on the right.
Name / vowel example: 위 (wi). Position: Below and to the right of the starting consonant.
Standard pronunciation allows a diphthong too.
Build: ㅇ + ㅟ → 위. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
ㅢ ui · example 의
Explore this letter: shape, build and practice
ㅡ below-left joins ㅣ on the right.
Name / vowel example: 의 (ui). Position: Below and to the right of the starting consonant.
One written vowel slot. Its pronunciation changes in some contexts; this is not a universal oo-ee rule.
Build: ㅇ + ㅢ → 의. Initial ㅇ supplies the written starting position without adding a consonant sound.
Copy, cover and redraw. Check the direction and number of short marks.
Try first: Which components distinguish ㅙ and ㅞ? Build each with initial ㅇ.
Check your answer and why
ㅙ = ㅗ + ㅐ and ㅞ = ㅜ + ㅔ. The blocks are 왜 (wae) and 웨 (we). Preserve the spelling even if a speaker’s sounds are similar.
Small session 4
Recall and rebuild
Close the cards before trying. This is a written recognition check, not a listening test.
Try first: Write the 11 additional vowels in groups of 4, 3 and 4.
Check your answer and why
ㅐ ㅒ ㅔ ㅖ / ㅘ ㅙ ㅚ / ㅝ ㅞ ㅟ ㅢ. The grouping is a study aid, not three pronunciation categories.
Try first: Build ㅇ + ㅖ, ㄴ + ㅟ, and ㅇ + ㅢ.
Check your answer and why
예 (ye), 뉘 (nwi), 의 (ui). Each is one syllable block. Initial ㅇ supplies the written starting position without adding a consonant sound.
Next-day recall: draw a right-side vowel, one combination using ㅗ, and one using ㅜ. Explain the differences before reopening the cards. Revisit only the small group you missed.
Optional review · two words in a small scene

Original AI-generated learning illustration retained from the earlier draft. Review familiar basic vowels here; this is not a new additional-vowel task.
In this scene, 나무 (namu) labels the living tree and 마루 (maru) the wooden floor—not the whole house. Both are nouns, not complete sentences. Word meanings depend on context.
마 + 루 → 마루
Try first: Build the wooden-floor word from ㅁ + ㅏ, then ㄹ + ㅜ. Which block goes first?
Check your answer and why
마루: 마 (ma) is side by side; 루 (ru) is stacked. Join the two blocks without a space. Reversing them does not preserve the taught word.
Try first: Cover the labels. Which word names the living tree? Split it into blocks.
Check your answer and why
나무 = 나 + 무. If spelling is correct but meaning is mixed up, revisit the scene rather than relearning every letter.
Earlier draft source record, checked October 27, 2026: NIKL’s Korean Basic Dictionary distinguishes tree and wood meanings for 나무; the Academy of Korean Studies architectural glossary documents floor and roof-ridge uses of 마루. The example uses the floor meaning only.
Keep your learning path small
Across Lessons 1–3, the written inventory is 19 consonants and 21 vowels. That is the modern alphabet, not all Korean pronunciation or vocabulary. Lesson 4 introduces batchim (final consonants). Review these open-syllable constructions before adding a final.
