History and etymology of kernel

The noun 'kernel' has an etymology that can be traced back to the Latin word 'carnalis,' which means pertaining to flesh or meat. In Late Latin, 'carnalis' evolved into 'kernelis,' referring to the innermost, central part of a nut or seed, which is often likened to the essence or core of such objects. This Latin root gave rise to the Old French term 'kernil' and eventually made its way into Middle English as 'kernell.' Over time, the word 'kernel' came to represent not only the inner part of a seed or nut but also the core, essential, or central part of anything, highlighting its evolution from a botanical term to a broader metaphorical concept.
