English → English (gcide) Definition: Radical Radical \Rad"i*cal\ (r[a^]d"[i^]*kal), a. [F., fr. L. radicalis having roots, fr. radix, -icis, a root. See Radix.] 1. Of or pertaining to the root; proceeding directly from the root. [1913 Webster] 2. Hence: Of or pertaining to the root or origin; reaching to the center, to the foundation, to the ultimate sources, to the principles, or the like; original; fundamental; thorough-going; unsparing; extreme; as, radical evils; radical reform; a radical party. [1913 Webster] The most determined exertions of that authority, against them, only showed their radical independence. --Burke. [1913 Webster] 3. (Bot.) (a) Belonging to, or proceeding from, the root of a plant; as, radical tubers or hairs. (b) Proceeding from a rootlike stem, or one which does not rise above the ground; as, the radical leaves of the dandelion and the sidesaddle flower. [1913 Webster] 4. (Philol.)

Radical pitch, the pitch or tone with which the utterance of a syllable begins. --Rush. Radical quantity (Alg.), a quantity to which the radical sign is prefixed; specifically, a quantity which is not a perfect power of the degree indicated by the radical sign; a surd. Radical sign (Math.), the sign [root] (originally the letter r, the initial of radix, root), placed before any quantity, denoting that its root is to be extracted; thus, [root]a, or [root](a + b). To indicate any other than the square root, a corresponding figure is placed over the sign; thus, [cuberoot]a, indicates the third or cube root of a.

[1913 Webster] Syn: Primitive; original; natural; underived; fundamental; entire. Usage: Radical, Entire. These words are frequently employed as interchangeable in describing some marked alteration in the condition of things. There is, however, an obvious difference between them. A radical cure, reform, etc., is one which goes to the root of the thing in question; and it is entire, in the sense that, by affecting the root, it affects in an appropriate degree the entire body nourished by the root; but it may not be entire in the sense of making a change complete in its nature, as well as in its extent. Hence, we speak of a radical change; a radical improvement; radical differences of opinion; while an entire change, an entire improvement, an entire difference of opinion, might indicate more than was actually intended. A certain change may be both radical and entire, in every sense. [1913 Webster] Radical \Rad"i*cal\ (r[a^]d"[i^]*kal), 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. [1913 Webster] 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. [1913 Webster] 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. [1913 Webster] In politics they [the Independents] were, to use the phrase of their own time, “Root-and-Branch men,” or, to use the kindred phrase of our own, Radicals. --Macaulay. [1913 Webster] 3. (Chem.) (a) A characteristic, essential, and fundamental constituent of any compound; hence, sometimes, an atom. [1913 Webster] As a general rule, the metallic atoms are basic radicals, while the nonmetallic atoms are acid radicals. --J. P. Cooke.
