Etymology
The word 'kernel' originates from the Old English cyrnel, a diminutive form of corn, which meant 'seed' or 'grain'. This Old English term is derived from Proto-Germanic kurnilaz, built on the root kurną (grain), which can be traced back to the Proto-Indo-European root ǵr̥h₂-nóm (grain). The literal sense of 'a small seed or grain' evolved metaphorically to denote the essential, central part within a hard shell, leading to its modern abstract meaning of the core or most vital element of an idea, system, or argument.
