Word origin
The word 핵 (haek, "core") is the Sino-Korean reading of a Chinese character meaning a kernel or central core, a sense extended into scientific terminology.
Usage tips
- Science lessons often contrast the central part with the whole cell or atom, which helps prevent confusion when reading diagrams.
