    In mathematics, a well-defined expression or unambiguous expression is an expression whose definition assigns it a unique interpretation or value. Otherwise, the expression is said to be not well defined, ill defined or ambiguous. [1]

  3. Problem solving - Wikipedia

    en.wikipedia.org/wiki/Problem_solving

    Well-defined problems have specific end goals and clearly expected solutions, while ill-defined problems do not. Well-defined problems allow for more initial planning than ill-defined problems. [ 2 ] Solving problems sometimes involves dealing with pragmatics (the way that context contributes to meaning) and semantics (the interpretation of the ...

    Thus, in order to achieve peace, one must eliminate the threat. This can be achieved by: destroying the enemy; changing one's perception of an entity as enemy; achieving the goal the enemy is frustrating. Personal conflicts are frequently either unexamined (one's goals are not well defined) or examined only from one point of view.

    The number of English words is not well-defined. You can pick your favorite dictionary and count the origins of its words. More instructive would be a graph of minimum-word-frequency against percentage-of-Romance-origin. As previous commentators suggest, the lower the tolerated frequency, the greater the proportion of Latin.

  7. Concept - Wikipedia

    en.wikipedia.org/wiki/Concept

    A concept is merely a symbol, a representation of the abstraction. The word is not to be mistaken for the thing. For example, the word "moon" (a concept) is not the large, bright, shape-changing object up in the sky, but only represents that celestial object. Concepts are created (named) to describe, explain and capture reality as it is known ...

  8. Phenotype - Wikipedia

    en.wikipedia.org/wiki/Phenotype

    A proposed definition for both terms as the "physical totality of all traits of an organism or of one of its subsystems" was put forth by Mahner and Kary in 1997, who argue that although scientists tend to intuitively use these and related terms in a manner that does not impede research, the terms are not well defined and usage of the terms is ...

  9. Well-formedness - Wikipedia

    en.wikipedia.org/wiki/Well-formedness

    For example, the nonce word wug coined by Jean Berko Gleason is phonologically well-formed, so informants are able to pluralize it regularly. [1] A word, phrase, clause, or utterance may be grammatically well-formed, meaning it obeys the rules of morphology and syntax. A semantically well-formed utterance or sentence is one that is meaningful ...
