What 랩 means
Check the whole word: rap in music, lab in science.
In everyday Korean, 랩 shows up in music talk as rap, as in 랩 음악. In technical talk it shortens English lab, as in 랩온어칩, meaning lab-on-a-chip. Alone it is just a sound block; the word beside it picks the meaning.
These blocks belong to Hangul, the Korean alphabet that stacks sounds into syllables. Its announcement is dated 1443, with the explanatory proclamation text dated 1446, made to write Korean speech directly.
