Consider the modal account in terms of the argument given as an example above: All frogs are green. Kermit is a frog. Therefore, Kermit is green. The conclusion is a logical consequence of the premises because we can not imagine a possible world where (a) all frogs are green; (b) Kermit is a frog; and (c) Kermit is not green.
For example, the sentence "The king of France is bald" presupposes that there is a king of France. Unlike an entailment, presuppositions survive when the sentence is negated. The negation test can be used to determine the difference between entailment and presupposition. [ 4 ]
Textual entailment can be illustrated with examples of three different relations: [5] An example of a positive TE (text entails hypothesis) is: text: If you help the needy, God will reward you. hypothesis: Giving money to a poor man has good consequences. An example of a negative TE (text contradicts hypothesis) is:
An argument (consisting of premises and a conclusion) is valid if and only if there is no possible situation in which all the premises are true and the conclusion is false. For example a valid argument might run: If it is raining, water exists (1st premise) It is raining (2nd premise) Water exists (Conclusion)
An example of that is the presupposition trigger too. This word triggers the presupposition that, roughly, something parallel to what is stated has happened. For example, if pronounced with emphasis on John, the following sentence triggers the presupposition that somebody other than John had dinner in New York last night.
In formal semantics, Strawson entailment is a variant of the concept of entailment which is insensitive to presupposition failures. Formally, a sentence P Strawson-entails a sentence Q iff Q is always true when P is true and Qs presuppositions are satisfied. For example, "Maria loves every cat" Strawson-entails "Maria loves her cat" because ...
The opposite is a prologue—a piece of writing at the beginning of a work of literature or drama, usually used to open the story and capture interest. [2] Some genres, for example television programs and video games, call the epilogue an "outro" patterned on the use of "intro" for "introduction".
Poetic closure is the sense of conclusion given at the end of a poem. Barbara Herrnstein Smith's detailed study—Poetic Closure: A Study of How Poems End—explores various techniques for achieving closure. One of the most common techniques is setting up a regular pattern and then breaking it to mark the end of a poem.
