Hangul Consonants in Korean

Overview

Korean consonants form the other half of the Hangul writing system, essential knowledge at the CEFR A1 level. There are 19 consonants in total: 14 basic consonants and 5 double (tense) consonants. Understanding consonants is critical because their pronunciation changes depending on their position within a syllable block — a feature that makes Korean phonology distinctive.

The consonant shapes were designed to represent the position of the tongue, lips, and throat during articulation. For example, ㄱ mimics the tongue touching the back of the mouth, while ㅁ represents the shape of closed lips. This systematic design means that consonants sharing similar shapes often share similar sounds.

Learning all 19 consonants alongside the 21 vowels gives you the complete toolkit to read any Korean text. The tense consonants (doubled forms) add an extra layer of expressiveness, distinguishing words that would otherwise sound identical.

How It Works

Basic Consonants (14)

Consonant	Initial Position	Final Position	Romanization
ㄱ	g	k	g/k
ㄴ	n	n	n
ㄷ	d	t	d/t
ㄹ	r	l	r/l
ㅁ	m	m	m
ㅂ	b	p	b/p
ㅅ	s	t	s
ㅇ	(silent)	ng	(ng)
ㅈ	j	t	j
ㅊ	ch	t	ch
ㅋ	k	k	k
ㅌ	t	t	t
ㅍ	p	p	p
ㅎ	h	(silent/varies)	h

Tense (Double) Consonants (5)

Consonant	Sound	Romanization
ㄲ	kk (tense, unaspirated)	kk
ㄸ	tt (tense, unaspirated)	tt
ㅃ	pp (tense, unaspirated)	pp
ㅆ	ss (tense)	ss
ㅉ	jj (tense)	jj

Aspirated vs. Tense vs. Plain

Korean distinguishes three types of stops:

Type	ㄱ-series	ㄷ-series	ㅂ-series	ㅈ-series
Plain	ㄱ (g)	ㄷ (d)	ㅂ (b)	ㅈ (j)
Aspirated	ㅋ (k)	ㅌ (t)	ㅍ (p)	ㅊ (ch)
Tense	ㄲ (kk)	ㄸ (tt)	ㅃ (pp)	ㅉ (jj)

Examples in Context

Korean	Romanization	English	Note
가	ga	go	plain ㄱ initial
카	ka	car (loanword sound)	aspirated ㅋ initial
까	kka	(tense sound)	tense ㄲ initial
나	na	I (casual)	ㄴ initial
다	da	all	ㄷ initial
바다	ba-da	sea	ㅂ + ㄷ
사람	sa-ram	person	ㅅ initial, ㄹ medial
집	jip	house	ㅈ initial, ㅂ final
학교	hak-gyo	school	ㅎ initial, ㄱ final
빵	ppang	bread	tense ㅃ
쓰다	sseu-da	to write / to be bitter	tense ㅆ
아빠	a-ppa	dad	tense ㅃ

Common Mistakes

Not distinguishing plain, aspirated, and tense

• Wrong: Pronouncing ㄱ, ㅋ, and ㄲ the same way
• Right: ㄱ is soft (between g and k), ㅋ has a strong puff of air, ㄲ is tight with no air
• Why: English only distinguishes voiced/voiceless, but Korean uses a three-way contrast that is crucial for meaning.

Ignoring final consonant sound changes

• Wrong: Pronouncing the ㅅ in 옷 as "s" (ot-s)
• Right: 옷 is pronounced "ot" — final ㅅ becomes a "t" sound
• Why: Only seven sounds are possible in final position: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅇ.

Confusing ㄹ as always "r" or always "l"

• Wrong: Always saying "r" for ㄹ
• Right: ㄹ is "r" (flap) at the start of a syllable and "l" at the end
• Why: Korean ㄹ is a liquid consonant that changes quality by position.

Overlooking ㅇ's dual role

• Wrong: Assuming ㅇ is always silent
• Right: ㅇ is silent as an initial consonant but pronounced "ng" as a final consonant
• Why: 강 (gang, "river") has ㅇ as a final consonant producing the "ng" sound.

Usage Notes

Consonant pronunciation is consistent in isolation, but in connected speech, numerous sound changes occur (linking, nasalization, tensification, aspiration). These are covered in the Pronunciation Rules concept. At the A1 level, focus on learning each consonant's basic sound in both initial and final positions.

Practice Tips

• Practice the three-way contrast (plain/aspirated/tense) by holding your hand in front of your mouth: aspirated consonants produce a noticeable puff of air, plain consonants produce a slight puff, and tense consonants produce no air at all.
• Write each consonant repeatedly while saying its name aloud. Korean children learn consonant names: 기역 (ㄱ), 니은 (ㄴ), 디귿 (ㄷ), etc.
• Pair consonants with simple syllables using all basic vowels to practice reading: 가, 거, 고, 구, 그, 기, then 나, 너, 노, 누, etc.
