Webster's 1913 Dictionary

Radical Rad"i*cal, n. 1. (Philol.) (a) A primitive word; a radix, root, or simple, underived, uncompounded word; an etymon. (b) A primitive letter; a letter that belongs to the radix. The words we at present make use of, and understand only by common agreement, assume a new air and life in the understanding, when you trace them to their radicals, where you find every word strongly stamped with nature; full of energy, meaning, character, painting, and poetry. --Cleland. 2. (Politics) One who advocates radical changes in government or social institutions, especially such changes as are intended to level class inequalities; -- opposed to conservative. In politics they [the Independents] were, to use phrase of their own time. ``Root-and-Branch men,'' or, to use the kindred phrase of our own, Radicals. --Macaulay. 3. (Chem.) (a) A characteristic, essential, and fundamental constituent of any compound; hence, sometimes, an atom. As a general rule, the metallic atoms are basic radicals, while the nonmetallic atoms are acid radicals. --J. P. Cooke. (b) Specifically, a group of two or more atoms, not completely saturated, which are so linked that their union implies certain properties, and are conveniently regarded as playing the part of a single atom; a residue; -- called also a compound radical. Cf. Residue. 4. (Alg.) A radical quantity. See under Radical, a. An indicated root of a perfect power of the degree indicated is not a radical but a rational quantity under a radical form. --Davies & Peck (Math. Dict.) 5. (Anat.) A radical vessel. See under Radical, a.
