Etymology

The word "nuclear" derives from the Latin "nucleus," meaning "kernel" or "core," which itself comes from "nux" (nut). The suffix "-ar" is a common English adjectival ending, indicating relation. Originally used in biology to describe cell nuclei, the term expanded in the 20th century to encompass atomic nuclei and energy, reflecting its core-centric logic.
