Hangul Syllable Blocks & Batchim

What it means

Korean letters are not written one after another in a line. They are grouped into square syllable blocks, and each block is one syllable. Batchim (받침) = the consonant written at the bottom of a block.

How to make it

• Consonant + vowel: 가 = ㄱ + ㅏ
• Starts with a vowel sound → put the silent ㅇ first: 아 = ㅇ + ㅏ, 우유 = 우 (ㅇ+ㅜ) + 유 (ㅇ+ㅠ)
• Consonant + vowel + batchim: 각 = ㄱ + ㅏ + ㄱ, 한국 = 한 (ㅎ+ㅏ+ㄴ) + 국 (ㄱ+ㅜ+ㄱ)

How to read batchim

• At the end of a syllable, batchim has only seven sounds: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅇ
• So many letters change sound. ㅅ, ㅈ, ㅊ, ㅌ, ㅎ, ㅆ all sound like ㄷ (a short 't'): 옷 → [옫], 낮 → [낟], 꽃 → [꼳]
• ㅋ and ㄲ sound like ㄱ (부엌 → [부억]); ㅍ sounds like ㅂ (앞 → [압])
• Batchim + a block that starts with silent ㅇ → the batchim moves over: 음악 → [으막], 한국어 → [한구거]

Why it matters

Whether a word ends in batchim decides which particle or ending you use in almost every grammar point.

• Ends in batchim: 책 → 책은, 책이, 책을, 학생이에요
• No batchim (ends in a vowel): 커피 → 커피는, 커피가, 커피를, 의사예요

Common mistakes

• ❌ ㅏ (a vowel alone) → ✅ 아 (every block needs a first consonant; use silent ㅇ)
• ❌ 꽃 read as "kkoch" → ✅ [꼳] "kkot" (ㅊ at the end sounds like ㄷ)
• ❌ 음악 read as 음 + 악 with a break → ✅ [으막] (the batchim slides into the empty ㅇ)
