Korean Alphabet Table

Three structural reasons, not flattery. First, it is featural: the letter shapes describe articulation, so ㅋ visibly being ㄱ with an extra stroke means "same place, more air" and ㄲ visibly being ㄱ twice means "same place, more tension" - the chart teaches its own logic. Second, only 24 basic letters produce every Korean sound, versus hundreds of characters in the scripts Hangul displaced. Third, letters assemble by rule into syllable blocks, so reading is chunked into syllable-sized pieces. The historical evidence agrees: a well-known 1940s study found Korean literacy jumped to near-universal within a generation of Hangul's modern revival, and the design predates the modern literacy-science that vindicates it by five centuries.

Korean neutralizes most final consonants into one of seven sounds - and the plosives all land on their unvoiced stop: ㄱ ends as k, ㄷ as t, ㅂ as p, no matter what they said at the start. That is why the table's romanization has two columns of truth: 방 is romanized bang but pronounced with a final k-like stop, 집 is jip not jib, 밥 is pap. The seven final sounds are ㄱㄴㄷㄹㅁㅂㅇ (k, n, t, l, m, p, ng); any other consonant written in final position collapses to one of these by rule, which is exactly what the RR system's k/t/p finals encode.

The five doubles (ㄲ ㄸ ㅃ ㅆ ㅉ) are tensed consonants, and the four aspirates (ㅋ ㅌ ㅍ ㅊ) are plain consonants plus an extra stroke - the two triples exist because Korean distinguishes three stop series where English has two. The plain ㄱ is voiced-ish between vowels and lightly aspirated; the aspirate ㅋ is a strong puff of air (hold a tissue in front of your mouth - it moves); the tense ㄲ is neither - it is a glottal-tightened, shorter, sharper release with no puff. English speakers hear tense sounds as "emphasized", which is the wrong model but a usable start: keep the throat constricted and the release short, and the tissue stays still.

Every Korean syllable is one square assembled from up to four jamo by fixed geometry: the initial consonant sits top-left (or left of a horizontal vowel), the vowel fills the right or below, and up to two final consonants (batchim) stack underneath. ㅇ is the silent filler for syllables that begin with a vowel, so the circle you see in 아 or 우 is a placeholder, not a sound. The math is large but finite: 19 possible initials, 21 vowels, and 28 final combinations (including "none") give 11,172 legal blocks - Unicode's Hangul syllable formulas encode all of them, and everyday text uses only a few hundred.

Revised Romanization (RR), the official South Korean system since 2000 - so 기역 is giyeok, not ki-yŏk; the older McCune-Reischauer system you will still meet in older maps and academic texts writes the same letter differently. RR's rule worth internalizing: it spells sounds by syllable position, so ㄱ is g in 가 but k in the final of 박, and ㄹ is r between vowels but l at a syllable's end or when doubled. That is not inconsistency - it mirrors how the letter actually sounds in each slot, which is why the table shows both readings per letter instead of pretending one romanization covers both.
