Etymology

Learned borrowing from Latin nucleus (“kernel, core”). The earliest uses refer to the head of a comet and the kernel of a seed, both recorded in Lexicon Technicum in 1704. The sense in atomic physics was coined by British scientist Michael Faraday in 1844 in a theoretical meaning.

Webster’s 1913

  1. noun A kernel; hence, a central mass or point about which matter is gathered, or to which accretion is made; the central or material portion; --used both literally and figuratively.
  2. noun The body or the head of a comet.

Etymology [L., a kernel, dim. fr. nux, nucis, nut. Cf. Newel post.]
