Definitions

  • WordNet 3.6
    • n analogy drawing a comparison in order to show a similarity in some respect "the operation of a computer presents and interesting analogy to the working of the brain","the models show by analogy how matter is built up"
    • n analogy an inference that if things agree in some respects they probably agree in others
    • n analogy the religious belief that between creature and creator no similarity can be found so great but that the dissimilarity is always greater; any analogy between God and humans will always be inadequate
    • ***
Webster's Revised Unabridged Dictionary
  • Interesting fact: St. Patrick never really drove out any snakes from Ireland. This story was an analogy of how he drove paganism out of Ireland
    • Analogy (Biol) A relation or correspondence in function, between organs or parts which are decidedly different.
    • Analogy A resemblance of relations; an agreement or likeness between things in some circumstances or effects, when the things are otherwise entirely different. Thus, learning enlightens the mind, because it is to the mind what light is to the eye, enabling it to discover things before hidden.
    • Analogy (Gram) Conformity of words to the genius, structure, or general rules of a language; similarity of origin, inflection, or principle of pronunciation, and the like, as opposed to anomaly.
    • Analogy (Geom) Proportion; equality of ratios.

Century Dictionary and Cyclopedia
    • n analogy In mathematics, an equation between ratios. This use is obsolete except in a few phrases, as Napier's analogies, which are four important formulas of spherical trigonometry.
    • n analogy An agreement, likeness, or proportion between the relations of things to one another; hence, often, agreement or likeness of things themselves. Analogy strictly denotes only a partial similarity, as in some special circumstances or effects predicable of two or more things in other respects essentially different: thus, when we say that learning enlightens the mind, we recognize an analogy between learning and light, the former being to the mind what the latter is to the eye, enabling it to discover things before hidden.
    • n analogy Specifically In logic, a form of reasoning in which, from the similarity of two or more things in certain particulars, their similarity in other particulars is inferred. Thus, the earth and Mars are both planets, nearly equidistant from the sun, not differing greatly in density, having similar distributions of seas and continents, alike in conditions of humidity, temperature, seasons, day and night, etc.; but the earth also supports organic life; hence Mars (probably) supports organic life—is an argument from analogy. See induction.
    • n analogy In grammar, conformity to the spirit, structure, or general rules of a language; similarity as respects any of the characteristics of a language, as derivation, inflection, spelling, pronunciation, etc.
    • n analogy In biology, resemblance without affinity; physiological or adaptive likeness between things morphologically or structurally unlike: the opposite of homology. Thus, there is an analogy between the wing of a bird and that of a butterfly, both being adapted to the same physiological purpose of flight, but there is no morphological relation between them. Analogy rests upon mere functional (that is, physiological) modifications; homology is grounded upon structural (that is, morphological) identity or unity. Analogy is the correlative of physiology, homology of morphology; but the two may be coincident, as when structures identical in morphology are used for the same purposes and are therefore physiologically identical.

    • n Analogy an-al′o-ji an agreement or correspondence in certain respects between things otherwise different—a resemblance of relations, as in the phrase, 'Knowledge is to the mind what light is to the eye:' relation in general: likeness: :
    • n Analogy an-al′o-ji (geom.) proportion or the equality of ratios
    • n Analogy an-al′o-ji (gram.) the correspondence of a word or phrase with the genius of a language, as learned from the manner in which its words and phrases are ordinarily formed: similarity of derivative or inflectional processes
