radicalis

Forms

rādīcālis (neuter rādīcāle); third-declension two-termination adjective^[1]

Etymology

It is from Latin rādīx (“root”) + -ālis.^[1][2][3] Conte calls it a Late Latin word.^[4]

The TLL connects it with a group of Romance words for roots, stumps and weeds, such as Middle French racheau and the late Spanish raigal, though Wartburg takes the Spanish word to come from raíz (“root”).^[2]

Earliest recorded meaning

It first appears in Augustine, in a figurative sense: “serving as a root”, primordial; he speaks of a Christian society that is in a way native and rooted in the Catholic Church, and of obedience practised as a root virtue.^[2][5][4]

Semantic evolution

Augustine and the theologians after him also use the adverb rādīcāliter “from the root”, of the whole human race condemned at its root in Adam.^[2]

In Medieval Latin it took on concrete senses: “of the root of a plant”, then of bodily organs and functions “vital, principal” (the neuter plural for the vital organs), and in general “belonging to the root, fundamental, essential”.^[6] Ecclesiastical Latin glosses it “rooted, having roots, essential”.^[7] English borrowed it in the late 14th century as radical, first meaning “originating in the root”.^[8]
