Early 18th century: from Latin, literally 'kernel, inner part', diminutive of nux, nuc- 'nut'.
The nucleus of something is literally its ‘little nut’. In Latin nucleus meant ‘kernel, inner part’, and was a diminutive of nux ‘nut’. Nucleus originally referred to the bright core at the centre of a comet's head, and then to the central part of the earth. Today its main technical meaning is ‘the positively charged central core of an atom’. This was identified by Sir Ernest Rutherford ( 1871–1937), regarded as the founder of nuclear physics, in 1911.
