Isaac in Korean 아이작
Korean media, baristas and the immigration office write Isaac as 아이작: three syllables, said a-i-jak. Here's how it's built, how to say it, and what people will call you.
Isaac letter by letter
Each Hangul block is one syllable, built from a consonant, a vowel and sometimes a final consonant underneath.
The final ㄱ in 작 is unreleased: stop the sound (k) without a puff of air.
- ㅇ at the top of 이 is silent, so 이 is just the vowel: i.
- Give all 3 syllables the same weight. Korean has no strong stress, so it's a-i-jak, evenly.
How Koreans would call you
Korean given names are almost always two syllables (after a one-syllable family name), so at 3 syllables 아이작 reads as a foreign name at a glance. In casual sentences Koreans often add 이 after a name that ends in a consonant: 아이작이 왔어 ("Isaac's here").
Why it's spelled 아이작
Spelled letter-by-letter you'd get 이사아크, but Korean media write 아이작, because the name is written the way it sounds, not the way it's spelled.
- The long i (as in "my") is spelled 아이: two beats in Korean, one in English.
- After a short vowel the final k tucks under the syllable as ㄱ, instead of getting its own syllable.
