The following are tables on the jamo of Hangul consonants and vowels, with the original forms in blue at the first row, and their derivatives (in form and having additional sounds) in the following rows. They are separted into a table of initials, table of vowels and one of finals.
Hangeul (also Hangul or Han'gŭl, previously Han-kul; 한글) is the native alphabet used to write the Korean language (as opposed to the non-native Hanja).
Of the basic consonants, ㅊ (chieut), ㅋ (kieuk), ㅌ (tieut), and ㅍ (pieup) are aspirated derivatives of ㅈ (jieut), ㄱ (gieok), ㄷ (digeut), and ㅂ (bieup) respectively, formed by combining the parent consonant with the jamo ㅎ (hieut).
The Hangul Society, originally found by Ju Si-gyeong, announced a proposal for a new morphophonemic orthography in 1933, which became the prototype of the contemporary orthographies in the North and South.
