How People Learn Languages?
 Baby
 Language, and then characters
 Adult
 Characters, and then language
 We are adults!
 Let’s learn Korean characters first.

 Kana (Japanese character) mixed with Chinese characters
 主にスラヴ諸語を表記するのに用いられる表音文字の体系の一種である。
伝統的には、正教会の宣教師キュリロスとメトディオスの兄弟がスラヴ
人に布教するためにギリシャ文字を元に考案されたとされるが、彼らが
実際に考案した文字はグラゴル文字であったらしい。しかし、グラゴル
文字はすぐに廃れたため、キリル文字が広く用いられるようになり、
キュリロスが作った文字であるという意味からキリル文字と呼ばれるよ
うになった

Hangul (Korean)
Terminology (1)
 Meaning-based character scheme maps a mean directly into a
character.
 E.g. Water (in meaning)  水 (in Chinese)
 Sound-based character scheme maps a mean into a sound,
and then maps the sound into a series of characters.
 E.g. Water (in meaning)  [wɔ́ːtəːr]  water (in English)
 E.g. Water (in meaning)  [mul]  물 (in Korean)
 E.g. Water (in meaning)  [tu bik]  tubig (in Tagalog)
Terminology (2)
 Syllable
 A unit of complete sound
 A segment of a spoken word consisting of one sound or of two or more sounds said as a
single unit of speech
 Examples of one-syllable words
 Sing, song, run, go, …
 Examples of two-syllable words
 Singing, forget, knowledge, …
 Examples of words with three or more syllables
 Philippines, remember, …
 Phoneme
 The smallest unit of sound in a language that has significance in distinguishing one word
from another
 A syllable can be divided into several phonemes.
 Two categories of phonemes
 Consonants (e.g. B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X,Y, Z (in Alphabet))
 Vowels (e.g. A, E, I, O, U (in Alphabet))
Evolution of Characters
 Characters have been evolved in the sequence of meaning-
based, syllable-based, and finally phoneme-based, even
though some languages still use meaning-based (China) or
syllable-based (Japan) characters.
 Why?
 To reduce the number of symbols (characters)
 The more there are symbols, the more it is difficult to learn.
 E.g.
 Chinese : 30,000 or more symbols
 Kana : 50 + 1 symbols
 Alphabet : 26 symbols
Uniqueness of Hangul
Unique Feature of Hangul (1)
 Hangul is phoneme-based, but it can represent syllables, too.
 Example
 English
 For “river”, we can identify only consonants (r, v, r) and vowels (i, e).
 There is no specification about syllables.
 Korean
 For “서울” (Seoul), we can identify two syllables (서, 울) firstly, and
then, one consonant (ㅅ) and one vowel (ㅓ) from 서 (Seo), and two
consonants (ㅇ, ㄹ) and one vowel (ㅜ) from 울 (ul).

Korean
 In English,
 If you do not learn a word, you may not read or write the word.
 E.g. School, Chair
 In Korean language,
 Even though you do not learn a word, you can read and write the
word.
Unique Feature of Hangul (2)
 Transparency (from Computer Science)
 The representation is transparent from its meaning in Korean
thanks to Hangul.
 You can learn reading and writing (Hangul) without the
knowledge about Korean words (vocabulary), whereas you
should learn reading and writing with English words
simultaneously.
 Reading & writing are separated from vocabulary in Korean,
but reading & writing are combined with vocabulary in
English.
 So, Hangul is very easy to learn, read and write.
Unique Feature of Hangul (3)
 Syllable-based representation scheme of Hangul enforces no exceptions. (There are some
exceptions, though)
 Thanks to Hangul, Korean language has a tendency to adapt itself as a pronunciation for a
word is changed.
 Adaptation example
 삯월세 (rent-fee) [sag-wol-se]  사글세 [sa-gl-se]
 Korean government changed the standard from 삯월세 to 사글세.
 English allows many exceptions.
 English do not adapt itself even though a pronunciation for a word is changed.
 Example
 School vs. Skul
 UK or USA governments do not change the word from SCHOOL to SKUL.
 Writing “school” but reading “skul” is still OK for them.
 The issues is not government officers’ attitude (diligentness or lazyness), but the
tendency by the characters (Hangul and Alphabet).
 There is no “spelling bee” competition in Korea.
 Because every Korean (except babies) is a spelling bee.
To Learn Hangul
 Symbols for Phonemes
 Consonants:
 ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ
 Vowels:
 ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ
 ㅐ, ㅒ, ㅔ, ㅖ
 ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ
 Rule of layout for consonants and vowels to represent
syllables ( distinguished from other characters)

 Con. : a consonant
Section I
Con. (M) Section III
Section II Vow. (B)
Vow. (B)
Section IV Section V
Con. (O) Con. (O)
 Vow. : a vowel
 M : mandatory
 B : at least one vowel in
sections II and III
 Vowels with a vertical bar (ㅏ,
ㅑ, ㅓ, ㅕ, ㅣ, …) locate at
section III.
 Vowels with a horizontal bar
(ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, …)
locate at section II.
 O : optional

ㅇ

ㅗ
Con. (O) Con. (O)
 오 [o]
Special Consonant - ㅇ
 When “ㅇ” is in section I, it
means “void”.
 오 [o]
 When “ㅇ” is in section IV,
it is a consonant with its
own sound, “ng”.
 송 [song]

What is Good Layout?
 The layout result should be a square if possible.
