Lucas in Korean 루커스
Korean media, baristas and the immigration office write Lucas as 루커스: three syllables, said ru-keo-seu. Here's how it's built, how to say it, and what people will call you.
Lucas letter by letter
Each Hangul block is one syllable, built from a consonant, a vowel and sometimes a final consonant underneath.
The opening ㄹ is a single light tap, halfway between an English r and l. Never roll it.
- 스 carries the filler vowel ㅡ (eu). Keep it short and light, almost just the consonant.
- ㅓ (eo) in 커 is the open "uh" of "sun", not an "o".
- Give all 3 syllables the same weight. Korean has no strong stress, so it's ru-keo-seu, evenly.
How Koreans would call you
Korean given names are almost always two syllables (after a one-syllable family name), so at 3 syllables 루커스 reads as a foreign name at a glance. With foreign names some Koreans skip 야 and just say 루커스 or 루커스 씨.
Why it's spelled 루커스
Spelled letter-by-letter you'd get 루캐스, but Korean media write 루커스, because the name is written the way it sounds, not the way it's spelled.
- The unstressed "uh" vowel is written ㅓ (eo), whatever letter English uses for it.
- Korean adds the vowel ㅡ to consonants that have no vowel of their own (스), which is why Lucas has 3 syllables in Korean.
