Tense Consonants: ㄲ ㄸ ㅃ ㅆ ㅉ

Produce the tense consonants ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and tell apart the three-way contrast between plain, aspirated, and tense sounds (가 vs 카 vs 까).

  1. Letter 1 of 5
    ㄲ
    쌍기역 kk (tense)

    Two ㄱ's side by side — tighten your throat and let no air escape, like the 'k' in sky rather than kite.

    토끼 tokki rabbit
    코끼리 kokkiri elephant

Say it out loud

어깨 eokkae shoulder

Listen, then repeat aloud. Matching the rhythm matters more than perfection.

Why? The hardest part: 가 vs 카 vs 까

Korean has three versions of many consonant sounds: plain (가, relaxed, no puff), aspirated (카, a strong puff of air), and now tense (까, tight and clipped). To make a tense sound, squeeze your throat and hold it tense for a split second — no puff of air escapes, and the sound comes out short and sharp, almost like you're gritting your teeth. English hints at this in words like sky, stop, and spy, where the 'k', 't', and 'p' are unaspirated compared to kite, top, and pie. This three-way contrast is genuinely the hardest part of Hangul pronunciation for English speakers, so don't worry if 가/카/까 sound identical at first — your ear will adjust with practice.

Why? Doubled letters, doubled tension

Each tense consonant is written by doubling its plain partner: ㄲ = two ㄱ, ㄸ = two ㄷ, ㅃ = two ㅂ, ㅆ = two ㅅ, and ㅉ = two ㅈ. Their names follow the same pattern too — 쌍기역, 쌍디귿, and so on, where 쌍 means 'twin' or 'pair'. Think of the doubling as a visual cue: double the letter, double the muscle tension in your throat when you say it.

Common questions

Why compare ㄲ ㄸ ㅃ to sky, stop, spy? They don't look similar at all.

Listen to the k in sky and the k in kite — they are not the same. After 's', English drops the puff of air, and that airless k is almost exactly the Korean ㄲ. The comparison isn't about spelling, it's about the puff. Add the tight, held-back feeling in your throat and you have it.
