The Korean alphabet, known as Hangul, consists of 14 basic consonants, 5 double consonants, and various double batchim combinations.
There are 14 basic consonants in Korean: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, ㅎ. These form the foundation of the Korean consonant system.
Double consonants are created by doubling certain basic consonants. There are 5 double consonants: ㄲ, ㄸ, ㅃ, ㅆ, ㅉ.
Double batchim are combinations of two consonants that can appear at the end of a syllable. Some common double batchim include: ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ.
Consonants can appear in three positions in a syllable: initial (syllable-initial), medial (before a vowel), and final (syllable-final). The pronunciation of some consonants changes depending on their position.
