Why Does Korean Spelling Sound Different?

Spelling gives a stable written form so you can recognize a word. Actual speech is shaped by the sounds next to it, so the same final letter may be heard differently in context.

This course begins with a final sound meeting the next initial sound. Keep the normal spelling in front of you while you predict and listen to the natural sound.

Spelling: the form you read and write.

Sound: the form you hear in connected speech.

A Korean syllable can be viewed through three positions: the first sound (초성), the middle vowel (중성), and the final sound (종성). The final position is the key starting point here because it can meet the next syllable's first sound.

We will name the surrounding environment without memorizing every later rule now.

First sound: the opening consonant.

Middle sound: the vowel.

Final sound: the closing position when a syllable has one.

The table keeps spelling and sound side by side. The bracketed form is a listening guide only; do not rewrite the word that way. Each reason is a map-level observation. Detailed rules for these environments come in later lessons.

Spelling · Sound · Why

국물 · [궁물] · A final sound meets a nasal neighbor.

옷이 · [오시] · The final consonant meets a following vowel.

학교 · [학꾜] · Neighboring consonants can strengthen the next sound.

같이 · [가치] · The following 이 can affect the preceding consonant.

좋아요 · [조아요] · ㅎ between vowels can weaken or disappear.

Use complete sentences without changing their spelling. First notice the target word, then listen for the sound inside the sentence.
