verifies the logical connectivity among the given premises and the conclusion. It does not focus on the truthfulness of the premises and the conclusion; verifies the logical connectivity between the premises and the conclusion without focusing on their truthfulness
Logical condition
verifies the actual truth or falsity of the given premise and the conclusion; verifies the actual truth or falsity of the given premises and the conclusion
Truth condition
Any true inference from a true preposition.
Logical relationship between two propositions such that the truth of the first proposition p guarantees the truth of the second preposition q also The falsity of q, guarantees the falsity of p
Entailment
is a semantic relationship between two propositions such that if and only if p is true then q is true too.
Entailment
It occurs when words have more than one meaning as commonly defined and understood. In simple words, keywords in the sentence may be read to mean different things.
Lexical Ambiguity
– It is a grammatical construct that results from difficulty of applying universal grammatical laws to sentence structure. To simply put, words are arranged in ways that produce different meanings
Syntactical Ambiguity
It is a composite ambiguity containing elements of both lexical and syntactical ambiguity. It occurs when words or phrases are used multiple times in a sentence but with different meanings each time it is used.
Inflective Ambiguity
mutual entailment of two propositions which can logically be expressed by a conjunction. P entails q and q entails p.
Synonym
If one proposition asserts the opposite of another in terms of entailment, p entails not q.
Contradiction
A standard entailment; a relationship between two propositions. P could entail q but q does not entail p. This entailment involves propositions that are in a hyponymy relationship. This hyponymy could include hierarchies such as color hierarchies.
inclusion

Static evaluation
abnormality profile of the linguistic items in terms of combination and interaction of elements of language in different context that may create ambiguity and connotative meaning.
Example: my toothbrush is pregnant
