Definition

A definition is a statement that explains the meaning of a term (a word, phrase, or other set of symbols). The term to be defined is the definiendum. A term may have many different senses or meanings. For each such specific sense, a definiens is a cluster of words that defines that term with reference to the speaker's immediate intended meaning.

For example, in formal languages like mathematics, a "stipulative" definition guides a specific discussion. A stipulative definition can only be disproved by showing a logical contradiction. But a "descriptive" definition can be shown to be "right" or "wrong" with reference to general usage.

A chief difficulty in the management of definitions is the necessity of using other terms that are already understood or whose definitions are easily obtainable. The use of the term in a simple example may suffice. A dictionary definition typically contains additional details, such an etymology, obsolete meanings, and the language or languages of its origin.

A precising definition extends the descriptive dictionary definition (lexical definition) of a term for a specific purpose by including additional criteria, which narrow the set of things that meet the definition.

C.L. Stevenson has identified persuasive definition as a form of stipulative definition which purports to state the "true" or "commonly accepted" meaning of a term, while in reality stipulating an altered use (perhaps as an argument for some specific belief). Stevenson has also noted that some definitions are "legal" or "coercive" — their object is to create or alter rights, duties, or crimes.

Famous quotes containing the word definition:

    ... if, as women, we accept a philosophy of history that asserts that women are by definition assimilated into the male universal, that we can understand our past through a male lens—if we are unaware that women even have a history—we live our lives similarly unanchored, drifting in response to a veering wind of myth and bias.
    Adrienne Rich (b. 1929)

    Perhaps the best definition of progress would be the continuing efforts of men and women to narrow the gap between the convenience of the powers that be and the unwritten charter.
    Nadine Gordimer (b. 1923)

    It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.”
    Jane Adams (20th century)
