n.   pl. a·nal·o·gies

    2. A comparison based on such similarity. See Synonyms at likeness.
  2. Biology Correspondence in function or position between organs of dissimilar evolutionary origin or structure.
  3. A form of logical inference or an instance of it, based on the assumption that if two things are known to be alike in some respects, then they must be alike in other respects.
  4. Linguistics The process by which words or morphemes are re-formed or created on the model of existing grammatical patterns in a language, often leading to greater regularity in paradigms, as evidenced by helped replacing holp and holpen as the past tense and past participle of help on the model of verbs such as yelp, yelped, yelped.

Analogy

A*nal"o*gy\, n.; pl. Analogies. [L. analogia, Gr. ?, fr. ?: cf. F. analogie. See Analogous.]

1. 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.

Note: Followed by between, to, or with; as, there is an analogy between these objects, or one thing has an analogy to or with another.

Note: Analogy is very commonly used to denote similarity or essential resemblance; but its specific meaning is a similarity of relations, and in this consists the difference between the argument from example and that from analogy. In the former, we argue from the mere similarity of two things; in the latter, from the similarity of their relations. --Karslake.

2. (Biol.) A relation or correspondence in function, between organs or parts which are decidedly different.

3. (Geom.) Proportion; equality of ratios.

4. (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. --Johnson.

analogy [(uh-nal-uh-jee)]

A comparison of two different things that are alike in some way (see metaphor and simile). An analogy attributed to Samuel Johnson is: “Dictionaries are like watches; the worst is better than none, and the best cannot be expected to go quite true.”

analogy

in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function-flying. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it. Analogy is one aspect of evolutionary biology and is distinct from homology (q.v.), the similarity of structures as a result of similar embryonic origin and development, considered strong evidence of common descent
