Surface Forms
Morphology
radical = radic + al
The mathematical sense ('root' under √) is directly related to the 'root' concept but is a technical usage and not transparently analysable from the surface form for average learners.
Etymology
Radical comes from the Latin radix, meaning 'root'. In math, a radical points to a 'root' (as with the √ sign), so the name shows we are finding a number's root.
