Morphology

radical = radic + al

This linguistic sense essentially means 'root' (the basic form after removing affixes), so its meaning corresponds directly to the base concept even though the combining form 'radic' is not a standalone English word.

Etymology

Radical comes from the Latin radix, meaning 'root'. In language study, the radical is the basic 'root' form of a word before you add prefixes or endings.
