Hangul Lessons: ㄷ = D/T and ㄸ= DD/TT
The letter ᄃ (digeut) is pronounced like a D or a T depending on where it is found in a word or syllable. At the start of a word it’s pronounced like T, start of a syllable it is pronounced like a D, and at the end of a word it’s pronounced like T. Yes that’s a bit confusing but it helps me to remember that D and T sound very similar in English too, think of how they sound right in the middle between a sharp T and a sharp D sound and you’ll find the right pronunciation.
ㄸ = DD/TT
The letter ㄸ (ssangdigeut) is a strong dd/tt sound.
