  • n. Chemistry The stated findings of such a separation or determination.
  • n. Mathematics A branch of mathematics principally involving differential and integral calculus, sequences, and series and concerned with limits and convergence.
  • n. Mathematics The method of proof in which a known truth is sought as a consequence of a series of deductions from that which is the thing to be proved.
  • n. Linguistics The use of function words such as prepositions, pronouns, or auxiliary verbs instead of inflectional endings to express a grammatical relationship; for example, the cover of the dictionary instead of the dictionary's cover.

  • n. A resolution of anything, whether an object of the senses or of the intellect, into its constituent or original elements; an examination of the component parts of a subject, each separately, as the words which compose a sentence, the tones of a tune, or the simple propositions which enter into an argument. It is opposed to synthesis.
  • n. The separation of a compound substance, by chemical processes, into its constituents, with a view to ascertain either (a) what elements it contains, or (b) how much of each element is present. The former is called qualitative, and the latter quantitative analysis.
  • n. The tracing of things to their source, and the resolving of knowledge into its original principles.
  • n. The resolving of problems by reducing the conditions that are in them to equations.
  • n.
  • n. A syllabus, or table of the principal heads of a discourse, disposed in their natural order.
  • n. A brief, methodical illustration of the principles of a science. In this sense it is nearly synonymous with synopsis.
  • n. The process of ascertaining the name of a species, or its place in a system of classification, by means of an analytical table or key.

from The Century Dictionary and Cyclopedia

  • n. The resolution or separation of anything which is compound, as a conception, a sentence, a material substance, or an event, into its constituent elements or into its causes; decomposition.
  • n. The regressive scientific method of discovery; research into causes; induction.
  • n. In mathematics: Originally, and still frequently, a regressive method, said to have been invented by Plato, which first assumes the conclusion and gradually leads back to the premises.
  • n. Algebraical reasoning, in which unknown quantities are operated upon in order to find their values.
  • n. The treatment of problems by a consideration of infinitesimals, or something equivalent, especially by the differential calculus (including the integral calculus, the calculus of variations, etc.): often called infinitesimal analysis. This is the common meaning of the word in modern times.
  • n. Hence — The discussion of a problem by means of algebra (in the sense of a system of symbols with rules of transformation), in opposition to a geometrical discussion of it, that is, a discussion resting directly upon the imagination of space: thus, analytical geometry is the treatment of geometrical problems by analysis.
  • n. A syllabus or synopsis of the contents of a book or discourse, or of the principles of a science.
  • n. In cricket, an itemized record of the play of the bowler, intended to show particularly the number of runs scored by him and the number of wickets obtained.
  • n. In chem., intentionally produced decomposition: often applied to the ascertainment of the composition of a substance, whether the constituents are actually obtained in separate form or not.

  • n. an investigation of the component parts of a whole and their relations in making up the whole
  • n. a form of literary criticism in which the structure of a piece of writing is analyzed
  • n. the use of closed-class words instead of inflections: e.g., `the father of the bride' instead of `the bride's father'
  • n. a set of techniques for exploring underlying motives and a method of treating various mental disorders; based on the theories of Sigmund Freud
  • n. a branch of mathematics involving calculus and the theory of limits; sequences and series and integration and differentiation
  • n. the abstract separation of a whole into its constituent parts in order to study the parts and their relations
