    • n root In botany, a part of the body of a plant which, typically, grows downward into the soil, fixes the plant, and absorbs nutriment. A root may be either a descending axis originating in germination from the lower end of the caulicle, and persisting as a tap-root, or one of a group of such roots—in either case called primary; or a branch of such a root, the ultimate ramifications forming rootlets or root-fibrils; or a similar organ developed from some other part of the plant (adventitious), sometimes with special functions—in the latter cases called secondary. The root differs from the stem in having no nodes and internodes, its branches appearing in no regular order, and, normally, in giving rise to no other organs, though, as in the pear and poplar, it may develop buds and thence suckers. In mode of growth the root is peculiar in elongating only or chiefly at the extremity, and at the same time in not building upon the naked apex, but in a stratum (the growing-point) just short of the apex under the protection of a cover or sheath—the root-cap (which see). Aside from securing the plant in position, the ordinary function of roots is the absorption of water with nutritive matter in solution from the soil, or, in the case of aquatics, wholly or partly from the water. This office is performed by imbibition through the cell-walls of the fresher root-surface, except that of the extreme tip, the absorbent surface being greatly increased by the production of root-hairs. (See root-hair.) Many roots, however—chiefly the tap-roots of biennials—serve the special purpose of storing nutriment for a second season, becoming thus much enlarged, as in the beet and turnip. Roots of this class must be distinguished from the rhizome, bulb, etc., which, though subterranean, are modifications of the stem. Numerous plants put forth aërial roots, eventually reaching the soil (banian, mangrove), serving as means of climbing (ivy, poison-ivy), or, in the case of epiphytes, part fastening the plant to a bough, part free in the air, whence they are capable of absorbing some moisture. The roots of a parasitic plant penetrate the tissues of the host-plant and draw their nutritive matter from it. True roots are confined to flowering plants and vascular cryptogams, the rhizoids of many lower plants in part taking their place. See annual, biennial, perennial. See also cuts under ivy, monocotyledonous, prothallium, and rhizome.
    • n root Specifically, an esculent root, as a beet or a carrot.
    • n root That which resembles a root in shape, position, or function; that from which anything springs. The part of anything that resembles the root of a plant in manner of growth, or as a source of nourishment, support, or origin; specifically, in anatomy and zoology, some part or organ like or likened to the root of a plant; the deepest or most fixed part of something embedded in another; a base, bottom, or supporting part: technically called radix: as, the root of a finger-nail or a tooth; the root of a nerve or a hair: often used in the plural, though the thing in fact is singular: as, to drag out a nail by the roots.
    • n root Hence— The bottom or lower part of anything; foundation.
    • n root The origin or cause of anything; source.
    • n root The basis of anything; ground; support.
    • n root In philology, an elementary notional syllable; that part of a word which conveys its essential meaning, as distinguished from the formative parts by which this meaning is modified; an element in a language, whether arrived at by analysis of words or existing uncombined, in which no formative element is demonstrable: thus, true may be regarded as the root of un-tru-th-ful-ness.
    • n root The first ancestor; an early progenitor.
    • n root In mathematics: The root of any quantity is such a quantity as, when multiplied into itself a certain number of times, will exactly produce that quantity. Thus, 2 is a root of 4, because when multiplied into itself it exactly produces 4. Power and root are correlative terms: the power is named from the number of the factors employed in the multiplication, and the root is named from the power. Thus, if a quantity be multiplied once by itself, the product is called the second power, or square, and the quantity itself the square root, or second root of the product; if the quantity be multiplied twice by itself, we obtain the third power, or cube, and the quantity is the cube root or third root; and so on. The character marking a root is √ (a modification of r for radix, which has been used probably since the middle of the sixteenth century), and the particular root is indicated by placing above the sign the figure which expresses the number of the root, which figure is called the index of the root. Thus, √16 indicates the fourth root of 16 (that is, 2), and √4 the square root of 4 (that is, 2)—the index in the case of the square root being usually omitted. The same is the case with algebraic quantities, as √ (a + 3ab + 3ab + b) = a + b. See power, index, involution, evolution. The root of an equation is a quantity which, substituted for the unknown quantity, satisfies the equation: thus, 2 + √2 is a root of the equation x—5x + 6x—2 = 0; for the sum of which is 0. Another root of the same equation is obviously 1; and the third root will be found to be 2—√2.
    • n root In music: With reference to a compound tone or a series of harmonics, the fundamental, generator, or ground tone. With reference to a chord, the fundamental tone—that is, the tone from whose harmonics the tones of the chord are selected, or the tone on which they are conceived to be built up. Theorists are not agreed as to what constitutes a root of a chord, or whether a chord may have two roots; and in many cases the term is used merely to designate the lowest tone of a chord when arranged in its simplest or normal position.
    • n root In chronology, the earliest time at which an event can take place, as a movable feast; also, the time at which any progressive change begins.
    • n root In astrology, the state of things at the beginning of any time; particularly, the figure of the heavens at the instant of birth, specifically called the root of nativity, a term also applied to the horoscope, or ascendant. Chaucer, in the passage below, has in mind the introduction to Zahel's treatise on Elections, where it is stated that elections of fortunate times for undertakings are not much to be depended upon, except in the case of kings, who have their roots of nativity (that is, in their case there is no doubt as to the precise aspect of the heavens at the moment of birth), which roots strengthen the inferences to be drawn, especially (at least so Chaucer understands the words) in the case of a journey. When the horoscope of birth was not known, astrologers were accustomed to determine elections chiefly by the place and phase of the moon, whose influence was, however, considered debile. It appears that in the case of the lady of the story, the moon was impedited in the root of nativity (see Almansor, Prop. 35: “Cum in radice nativitatis impedietur luna,” etc.), and Mars, a planet most unfavorable to journeys, was at azir, or lord of the ascendant, at her birth, and was in the fourth, or darkest, house; so that the omens of the journey were as gloomy as they well could be.
