A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. [2] For example, in the English language , the words begin , start , commence , and initiate are all synonyms of one another: they are synonymous .
In logic and mathematics, necessity and sufficiency are terms used to describe a conditional or implicational relationship between two statements.For example, in the conditional statement: "If P then Q", Q is necessary for P, because the truth of Q is guaranteed by the truth of P.
The concept of "necessary evil" is an idea that must be thoroughly rejected. Evil is not necessary, and to accept it as such is to perpetuate it. Evil must be opposed, rejected, and avoided at all costs. It should never be viewed as something that we must unavoidably and inevitably participate in. We trivialize evil when we refer to it as ...
In writing, phrases commonly used as alternatives to P "if and only if" Q include: Q is necessary and sufficient for P, for P it is necessary and sufficient that Q, P is equivalent (or materially equivalent) to Q (compare with material implication), P precisely if Q, P precisely (or exactly) when Q, P exactly in case Q, and P just in case Q.

A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
In logic, contingency is the feature of a statement making it neither necessary nor impossible. [1] [2] Contingency is a fundamental concept of modal logic.Modal logic concerns the manner, or mode, in which statements are true.
Amor fati is a Latin phrase that may be translated as "love of fate" or "love of one's fate".It is used to describe an attitude in which one sees everything that happens in one's life, including suffering and loss, as good or, at the very least, necessary.
The commonly employed system S5 simply makes all modal truths necessary. For example, if p is possible, then it is "necessary" that p is possible. Also, if p is necessary, then it is necessary that p is necessary. Other systems of modal logic have been formulated, in part because S5 does not describe every kind of modality of interest.
