Hangul (한글) has just 24 basic letters — 14 consonants and 10 vowels — and you can learn to read it in a single sitting. Unlike Chinese characters, Hangul is an alphabet: letters represent sounds and stack into syllable blocks. This is Lesson 1 of the kfluent curriculum, and the only one written mostly in English — from here on, you read Korean.

Why Hangul is the easiest part of Korean

Hangul was invented in 1443 by King Sejong specifically so ordinary people could learn it fast. The shapes are not random: consonants draw the shape of your mouth and tongue making the sound, and vowels are built from three philosophical strokes — a dot (sun), a horizontal line (earth), a vertical line (person).

The 10 basic vowels (모음)

ㅏ
a
as in father
아 — a
ㅓ
eo
as in up, uh
어 — eo
ㅗ
o
as in go (rounded)
오 — o
ㅜ
u
as in moon
우 — u
ㅡ
eu
as in good (lips flat!)
으 — eu
ㅣ
i
as in see
이 — i
ㅑ
ya
ㅣ+ㅏ — yah
야 — ya
ㅕ
yeo
ㅣ+ㅓ — yuh
여 — yeo
ㅛ
yo
ㅣ+ㅗ — yo
요 — yo
ㅠ
yu
ㅣ+ㅜ — you
유 — yu

Spot the system: add one stroke to ㅏㅓㅗㅜ and you get the y- versions ㅑㅕㅛㅠ. Ten letters, five sounds to memorize twice.

The 14 basic consonants (자음)

ㄱ
g/k
back of tongue blocks throat
가 — ga
ㄴ
n
tongue touches upper gums
나 — na
ㄷ
d/t
tongue tap, like d
다 — da
ㄹ
r/l
between r and l
라 — ra
ㅁ
m
closed lips — the square IS your lips
마 — ma
ㅂ
b/p
lips pop open
바 — ba
ㅅ
s
soft s
사 — sa
ㅇ
– / ng
silent at start, -ng at end
아 / 앙 — a / ang
ㅈ
j
like j in juice
자 — ja
ㅊ
ch
ㅈ + puff of air
차 — cha
ㅋ
k
ㄱ + puff of air
카 — ka
ㅌ
t
ㄷ + puff of air
타 — ta
ㅍ
p
ㅂ + puff of air
파 — pa
ㅎ
h
gentle h
하 — ha

Another pattern: ㅊㅋㅌㅍ are just ㅈㄱㄷㅂ with an extra stroke = an extra puff of air (aspiration). Hold your palm in front of your mouth — you should feel the puff.

HOW SYLLABLE BLOCKS WORK
자음 + 모음 = 글자

Korean never writes letters in a flat line — every syllable is packed into a square block, always starting with a consonant. Vertical vowels (ㅏㅓㅣ…) go to the right of the consonant: ㄴ+ㅏ = 나. Horizontal vowels (ㅗㅜㅡ…) go below: ㄴ+ㅗ = 노. No consonant sound to start with? Use silent ㅇ: ㅏ alone is written 아.

📖 READING PRACTICE — real words, letters you just learned Lesson 1

나 (na) — I, me · 어머니 (eo-meo-ni) — mother · 아이 (a-i) — child · 우유 (u-yu) — milk · 나무 (na-mu) — tree · 바다 (ba-da) — sea · 가수 (ga-su) — singer · 피자 (pi-ja) — pizza

Read each one out loud, left to right, block by block. If you got 피자, congratulations — you just read Korean.

FAQ

How long does it take to learn Hangul? Most learners read slowly within 2–3 hours and comfortably within a week of short daily practice. Hangul was designed in 1443 to be easy: King Sejong’s scholars described it as learnable “in a morning”.

Do I need to learn Hanja (Chinese characters) to read Korean? No. Modern Korean is written almost entirely in Hangul. Hanja appears only occasionally in newspapers, academic texts, or to clarify names.

Should I learn romanization instead of Hangul? No — romanization is a crutch that breaks down fast (Korean has sounds English letters can’t show). Learn Hangul first; every lesson on this site shows romanization only as training wheels.
