πŸ‡°πŸ‡· Lesson 1: Hangul Consonants

🎯 What You'll Learn

The Korean alphabet (ν•œκΈ€, Hangul) is one of the most scientific writing systems ever created. In this lesson you'll master all 19 consonants β€” 14 basic and 5 double (tense) consonants.

Estimated Time: 45–60 minutes

πŸ“– The Story of Hangul

Hangul was created in 1443 by King Sejong the Great so that ordinary people could read and write. Before Hangul, Korea used Chinese characters (ν•œμž), which required years of study. Sejong designed Hangul to be so logical that "a wise person can learn it in one morning, and even a fool can learn it in ten days."

πŸ’‘ Fun Fact: Hangul's consonant shapes are based on the shape of the mouth, tongue, and throat when making each sound. It's literally a diagram of how you speak!

πŸ”€ The 14 Basic Consonants

Korean has 14 basic consonant letters. Each has a name and represents a specific sound. Pay attention to how the sound can change depending on its position in a syllable.

LetterNameInitial SoundFinal Sound (λ°›μΉ¨)Think Of
γ„±κΈ°μ—­ (giyeok)g (as in go)kThe letter mimics the tongue touching the back of the mouth
γ„΄λ‹ˆμ€ (nieun)n (as in no)nTongue touching the roof of the mouth
γ„·λ””κ·Ώ (digeut)d (as in do)tTongue against the upper teeth ridge
ㄹ리을 (rieul)r/l (between the two)lTongue curls β€” a soft flap like the "t" in American "butter"
γ…λ―ΈμŒ (mieum)m (as in mom)mShape of closed lips
ㅂ비읍 (bieup)b (as in bus)pShape of the mouth from the side
γ……μ‹œμ˜· (siot)s (as in sun)tShape of a tooth
ㅇ이응 (ieung)silent (placeholder)ngShape of the throat β€” silent at start, "ng" at end
γ…ˆμ§€μ’ (jieut)j (as in joy)tA softer "j" than in English
γ…ŠμΉ˜μ“ (chieut)ch (as in chin)tγ…ˆ + extra breath (aspiration mark on top)
ㅋ킀읔 (kieuk)k (as in kite)kγ„± + extra breath
γ…Œν‹°μ• (tieut)t (as in top)tγ„· + extra breath
ㅍ피읖 (pieup)p (as in park)pγ…‚ + extra breath
γ…Žνžˆμ— (hieut)h (as in hat)silent/tShape of air flowing from the throat

βœ… Pattern to Notice

Plain β†’ Aspirated: Some consonants come in pairs. The aspirated version adds a puff of air (hold your hand in front of your mouth β€” you'll feel it):

γ„± (g) β†’ γ…‹ (k)  Β·  γ„· (d) β†’ γ…Œ (t)  Β·  γ…‚ (b) β†’ ㅍ (p)  Β·  γ…ˆ (j) β†’ γ…Š (ch)

πŸ’ͺ The 5 Double (Tense) Consonants

Double consonants are written by repeating the basic consonant. They're pronounced with a tight, tense throat β€” no puff of air, but with extra force. English doesn't really have this sound, so it takes practice!

LetterNameSoundExample
γ„²μŒκΈ°μ—­ (ssang-giyeok)Hard "kk" β€” no breath까 (kka)
γ„ΈμŒλ””κ·Ώ (ssang-digeut)Hard "tt" β€” no breathλ”° (tta)
γ…ƒμŒλΉ„μ (ssang-bieup)Hard "pp" β€” no breathλΉ  (ppa)
γ…†μŒμ‹œμ˜· (ssang-siot)Hard "ss" β€” no breathμ‹Έ (ssa)
γ…‰μŒμ§€μ’ (ssang-jieut)Hard "jj" β€” no breath짜 (jja)

⚠️ The Three-Way Distinction

Korean has three types of consonants for each group β€” this is the trickiest part for English speakers:

Plain (lax): γ„± γ„· γ…‚ γ…ˆ β€” gentle, soft start

Aspirated (breathy): γ…‹ γ…Œ ㅍ γ…Š β€” with a puff of air

Tense (doubled): γ„² γ„Έ γ…ƒ γ…‰ γ…† β€” tight throat, no air

Practice by holding a tissue in front of your mouth: the tissue should flutter for aspirated, not for tense, and barely for plain.

🧠 How Consonant Shapes Were Designed

King Sejong based the five basic shapes on how sounds are physically produced:

Base ShapeRepresentsRelated Consonants
γ„±Tongue touching the back of the mouth (velar)γ„± β†’ γ…‹ β†’ γ„²
γ„΄Tongue touching the roof of the mouth (alveolar)γ„΄ β†’ γ„· β†’ γ…Œ β†’ γ„Έ
ㅁShape of closed lips (bilabial)ㅁ β†’ γ…‚ β†’ ㅍ β†’ γ…ƒ
γ……Shape of a tooth (fricative)γ…… β†’ γ…ˆ β†’ γ…Š β†’ γ…† β†’ γ…‰
γ…‡Shape of the throat (glottal)γ…‡ β†’ γ…Ž

✍️ Practice: Identify the Consonant

🎯 Quick Quiz

Q1: Which consonant is silent at the beginning of a syllable but sounds like "ng" at the end?

Q2: What's the aspirated partner of γ„±?

Q3: How do you write a tense "ss" sound?

πŸ“ Writing Practice

Try writing each consonant by hand (on paper or a tablet). Follow this order for each group:

Round 1 β€” Basic consonants

γ„± γ„΄ γ„· γ„Ή ㅁ γ…‚ γ…… γ…‡ γ…ˆ

Write each one 5 times. Say its name and sound as you write.

Round 2 β€” Aspirated consonants

γ…Š γ…‹ γ…Œ ㅍ γ…Ž

Notice how each builds on a basic shape by adding strokes.

Round 3 β€” Double (tense) consonants

γ„² γ„Έ γ…ƒ γ…† γ…‰

Practice the tight throat feeling. No puff of air!
