Double Consonants (Tense Consonants)

Quick Reference

5 Double Consonants (경음/쌍자음) - Created by doubling basic consonants:

Basic Double Sound Change Example Word
k → hard k 까다 (to peel)
t/d → hard t 따다 (to pick)
p/b → hard p 빠다 (to suck)
s → hard s 싸다 (to wrap/to be cheap)
j → hard j 짜다 (to squeeze/to be salty)

Detailed Explanation

Double consonants (쌍자음), also called tense consonants (경음), are pronounced with more tension in the throat and without aspiration. They are formed by simply doubling the basic consonant.

What Makes Them "Tense"?

Physical characteristics: 1. Glottal tension: The throat muscles tighten 2. No aspiration: No puff of air (unlike ㅋ, ㅌ, ㅍ, ㅊ) 3. Shorter, sharper sound: More forceful articulation 4. Higher pitch: Often pronounced with slightly higher pitch

Testing aspiration: - Hold your hand in front of your mouth - : Small puff of air - : Large puff of air - : No puff of air

When Double Consonants Appear

Initial Position

Most common position for double consonants: - 까다 (to peel) - 빵 (bread) - 쌀 (rice)

After Final Consonant (Sound Change)

Double consonants can appear through sound changes (경음화): - 학교 → [학꾜] (school) - 잡지 → [잡찌] (magazine) - 국가 → [국까] (nation)

(More details in Sound Changes)

Never in Final Position

Double consonants never appear as final consonants (받침). Only single consonants can be final consonants.

Writing Double Consonants

Important rules: 1. Write them as two separate but close letters: ㄲ, ㄸ, ㅃ, ㅆ, ㅉ 2. They occupy the same space as a single consonant in the syllable block 3. In vertical vowel syllables: Double consonant on left, vowel on right (까, 빠) 4. In horizontal vowel syllables: Double consonant on top, vowel below (꼬, 뿌)

Examples: - 까 = ㄲ + ㅏ (not ㄱㄱ + ㅏ) - 빵 = ㅃ + ㅏ + ㅇ - 쌀 = ㅆ + ㅏ + ㄹ
