The following tables of consonants and vowels (jamo) of the Korean alphabet (Hangul) display (in blue) the basic forms in the first row and their derivatives in the following row(s). They are divided into initials (leading consonants), vowels (middle), and finals tables (trailing consonants).

The jamo shown below are individually romanized according to the Revised Romanization of Hangeul (RR Transliteration), which is a system of transliteration rules between the Korean and Roman alphabets, originating from South Korea. However, the tables below are not sufficient for normal transcription of the Korean language as the overarching Revised Romanization of Korean system takes contextual sound changes into account.

Called choseong, or "initials", there are 19 initial consonants, whereof one (ㅇ) is silent, and five (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) are doubled:

Called jungseong, or "vowels", there are 21 medial vowels:

Called jongseong, or "finals", there are 27 final consonants; with the additional case of no final consonant, there is a total of 28 possibilities:

Several collation sequences are used to order words (like alphabetical sorting). The North and South differ on (a) the treatment of composite jamo consonants in syllable-leading (choseong) and -trailing (jongseong) position, and (b) on the treatment of composite jamo vowels in syllable-medial (jungseong) position.

This first sequence is official in South Korea (and is the basic binary order of codepoints in Unicode):

Sequences of this second type are common in North Korea:

With 19 possible initial consonants, 21 possible medial (one- or two-letter) vowels, and 28 possible final consonants (of which one corresponds to the case of no final consonant), there are a total of 19 × 21 × 28 = 11,172 theoretically possible "Korean syllable letters" (Korean: 글자; RR: geulja; lit. letter) which are contiguously encoded in the 11,172 Unicode code points from U+AC00 (Decimal: 44,032₁₀) through U+D7A3 (Decimal: 55,203₁₀= 44,032 + 11,171) within the Hangul Syllables Unicode block. However, the majority of these theoretically possible syllables do not correspond to syllables found in actual Korean words or proper names.
