— Overview
This account maps types of Korean phonological change, and says they arise because spelling and pronunciation are not the same, in the course of making articulation easier. The types listed include coda neutralization, tensification, alveolar nasalization, liquidization, nasalization, labialization, velarization, palatalization, umlaut, vowel harmony, glide formation, consonant-cluster simplification, identical-vowel deletion, glide deletion, glide insertion, and vowel contraction.
Coda neutralization is described in more detail: a difficult obstruent in syllable-final position changes to one of ㄱ, ㅂ, or ㄷ — ㄲ and ㅋ to ㄱ, ㅍ to ㅂ, and other consonants to ㄷ. The text cites pronunciations such as 돼지국밥 said as 돼지국빱, and 믿고 said as 믿꼬, as cases where spelling and pronunciation part company. Those examples are left as the text cites them. Examples for the other types are not invented here.
— Contents and key concepts
A list of changes, and a reason close to speech
The starting point of this account is ordinary and practical. Korean spelling and Korean pronunciation are not the same, and phonological changes arise in the course of making articulation easier. Two sounds meet, and the shape of one of them changes. The list is long, and it is given as a map rather than as a full set of drills: coda neutralization, tensification, alveolar nasalization, liquidization, nasalization, labialization, velarization, palatalization, umlaut, vowel harmony, glide formation, consonant-cluster simplification, identical-vowel deletion, glide deletion, glide insertion, and vowel contraction.
Only one of those types is described in any detail here. The others remain names on the map. Worked examples for them are not invented.
Coda neutralization, and the examples as cited
Coda neutralization, as this account defines it, is what happens when a difficult obstruent stands in syllable-final position. It changes to one of the plain stops ㄱ, ㅂ, or ㄷ. Tense or aspirated velars ㄲ and ㅋ become ㄱ. The labial ㅍ becomes ㅂ. Other consonants become ㄷ. That rule is the heart of the description, and it is the rule a teacher can put on the board first, with the three landing places made visible.
The text then cites two pronunciations as cases where spelling and pronunciation part company: 돼지국밥 said as 돼지국빱, and 믿고 said as 믿꼬. Those examples are left as the text cites them, without adding further forms. A modest way to teach the item follows from the definition itself: start with the three landing places, let learners hear how a final consonant is realized, and only then bring in the cited pronunciations as reminders that what is written and what is said are not always the same. The page stops there.
