Jack in Korean 잭
Korean media, baristas and the immigration office write Jack as 잭: one syllable, said jaek. Here's how it's built, how to say it, and what people will call you.
Jack 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 잭 is unreleased: stop the sound (k) without a puff of air.
- ㅐ (ae) is said like the e in "bed" by most Koreans today, a little more closed than the a in "cat".
- ㅈ at the start is soft and unvoiced, halfway between ch and j.
- It's a single syllable in Korean, so say it in one short beat: jaek.
How Koreans would call you
One syllable is short for Korea, where given names are almost always two, so 잭 stands out and is easy to remember. In casual sentences Koreans often add 이 after a name that ends in a consonant: 잭이 왔어 ("Jack's here").
Why it's spelled 잭
Here the letters and the sound line up: applying the loanword rules letter by letter already gives 잭, the same spelling Korean media use.
- After a short vowel the final k tucks under the syllable as ㄱ, instead of getting its own syllable.
