LVT (첫가끝)

A Hangul syllable consists of Hangul jamo (Hangul letters).
Hangul letters are classified into three classes:
-  CHOSEONG  (the initial sound) as a leading consonant (L),
-  JUNGSEONG (the medial sound)  as a vowel (V),
-  JONGSEONG (the final sound)   as a trailing consonant (T).
Any Hangul syllable is a composition of (i) L + V, or (ii) L + V + T.
