Epistemic Modality
Epistemic modality is a sub-type of linguistic modality that encompasses knowledge, belief, or credence in a proposition. Epistemic modality is exemplified by the English modal verb, modals ''may'', ''might'', ''must''. However, it occurs cross-linguistically, encoded in a wide variety of lexical items and grammatical structures. Epistemic modality has been studied from many perspectives within linguistics and philosophy. It is one of the most studied phenomena in formal semantics (linguistics), formal semantics.

Linguistic Modality
In linguistics and philosophy, modality refers to the ways language can express various relationships to reality or truth. For instance, a modal expression may convey that something is likely, desirable, or permissible. Quintessential modal expressions include modal auxiliaries such as "could", "should", or "must"; modal adverbs such as "possibly" or "necessarily"; and modal adjectives such as "conceivable" or "probable". However, modal components have been identified in the meanings of countless natural language expressions, including counterfactuals, propositional attitudes, evidentials, habituals, and generics. Modality has been intensely studied from a variety of perspectives. Within linguistics, typological studies have traced crosslinguistic variation in the strategies used to mark modality, with a particular focus on its interaction with tense–aspect–mood marking. Theoretical linguists have sought to analyze both the propositional content and discourse effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominalization
In linguistics, nominalization or nominalisation, also known as nouning, is the use of a word that is not a noun (e.g., a verb, an adjective or an adverb) as a noun, or as the head (linguistics), head of a noun phrase. This change in functional category can occur through morphology (linguistics), morphological transformation, but it does not always. Nominalization can refer, for instance, to the of producing a noun from another part of speech by adding a derivation (linguistics), derivational affix (e.g., the noun "legalization" from the verb "legalize"), but it can also refer to the complex noun that is formed as a result. Some languages simply allow verbs to be used as nouns without inflectional difference (conversion (word formation), conversion or zero derivation), while others require some form of morphology (linguistics), morphological transformation. English language, English has cases of both. Nominalization is a natural language, natural part of language, but some insta ...

Epistemology
Epistemology is the branch of philosophy that examines the nature, origin, and limits of knowledge. Also called "the theory of knowledge", it explores different types of knowledge, such as propositional knowledge about facts, practical knowledge in the form of skills, and knowledge by acquaintance as a familiarity through experience. Epistemologists study the concepts of belief, truth, and justification to understand the nature of knowledge. To discover how knowledge arises, they investigate sources of justification, such as perception, introspection, memory, reason, and testimony. The school of skepticism questions the human ability to attain knowledge while fallibilism says that knowledge is never certain. Empiricists hold that all knowledge comes from sense experience, whereas rationalists believe that some knowledge does not depend on it. Coherentists argue that a belief is justified if it coheres with other beliefs. Foundationalists, by contrast, maintain th ...

Epistemic Logic
Epistemic modal logic is a subfield of modal logic that is concerned with reasoning about knowledge. While epistemology has a long philosophical tradition dating back to Ancient Greece, epistemic logic is a much more recent development with applications in many fields, including philosophy, theoretical computer science, artificial intelligence, economics, and linguistics. While philosophers since Aristotle have discussed modal logic, and Medieval philosophers such as Avicenna, Ockham, and Duns Scotus developed many of their observations, it was C. I. Lewis who created the first symbolic and systematic approach to the topic, in 1912. It continued to mature as a field, reaching its modern form in 1963 with the work of Saul Kripke. Historical development Many papers were written in the 1950s that spoke of a logic of knowledge in passing, but the Finnish philosopher G. H. von Wright's 1951 paper titled ''An Essay in Modal Logic'' is seen as a founding document. It was not unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alethic Modality
Alethic modality (from Greek ἀλήθεια = truth) is a linguistic modality that indicates modalities of truth, in particular the modalities of logical necessity, contingency, possibility and impossibility. Alethic modality is often associated with epistemic modality in research, and it has been questioned whether this modality should be considered distinct from epistemic modality which denotes the speaker's evaluation or judgment of the truth. The criticism states that there is no real difference between "the truth in the world" (alethic) and "the truth in an individual's mind" (epistemic). An investigation has not found a single language in which alethic and epistemic modalities would be formally distinguished, for example by the means of a grammatical mood. In such a language, "A circle can't be square", "can't be" would be expressed by an alethic mood, whereas for "He can't be that wealthy", "can't be" would be expressed by an epistemic mood. As we can see, this is not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evidentiality
In linguistics, evidentiality is, broadly, the indication of the nature of evidence for a given statement; that is, whether evidence exists for the statement and if so, what kind. An evidential (also verificational or validational) is the particular grammatical element (affix, clitic, or particle) that indicates evidentiality. Languages with only a single evidential have had terms such as mediative, médiatif, médiaphorique, and indirective used instead of ''evidential''. Evidentiality may be direct or indirect: direct evidentials are used to describe information directly perceived by the speaker through vision as well as other sensory experiences while indirect evidentials consist of the other grammatical markers for evidence such as quotatives and inferentials. Introduction All languages have some means of specifying the source of information. European languages (such as Germanic and Romance languages) often use modal verbs (, , , ) or other lexicon, lexical words (adverb ...

Quantifier (linguistics)
In formal semantics, a generalized quantifier (GQ) is an expression that denotes a set of sets. This is the standard semantics assigned to quantified noun phrases. For example, the generalized quantifier ''every boy'' denotes the set of sets of which every boy is a member: \ This treatment of quantifiers has been essential in achieving a compositional semantics for sentences containing quantifiers. Type theory A version of type theory is often used to make the semantics of different kinds of expressions explicit. The standard construction defines the set of types recursively as follows: #''e'' and ''t'' are types. #If ''a'' and ''b'' are both types, then so is \langle a,b\rangle #Nothing is a type, except what can be constructed on the basis of lines 1 and 2 above. Given this definition, we have the simple types ''e'' and ''t'', but also a countable infinity of complex types, some of which include: \langle e,t\rangle;\qquad \langle t,t\rangle;\qquad \langle\langle e,t\rangl ...

Relative Clauses
A relative clause is a clause that modifies a noun or noun phrase and uses some grammatical device to indicate that one of the arguments in the relative clause refers to the noun or noun phrase. For example, in the sentence ''I met a man who wasn't too sure of himself'', the subordinate clause ''who wasn't too sure of himself'' is a relative clause since it modifies the noun ''man'' and uses the pronoun ''who'' to indicate that the same "MAN" is referred to in the subordinate clause (in this case as its subject). In many languages, relative clauses are introduced by a special class of pronouns called ''relative pronouns'', such as ''who'' in the example just given. In other languages, relative clauses may be marked in different ways: they may be introduced by a special class of conjunctions called ''relativizers'', the main verb of the relative clause may appear in a special morphological variant, or a relative clause may be indicated by word order alone. In some languages, more t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conditional Clause
A conditional sentence is a sentence in a natural language that expresses that one thing is contingent on another, e.g., "If it rains, the picnic will be cancelled." They are so called because the impact of the sentence’s main clause is ''conditional'' on a subordinate clause. A full conditional thus contains two clauses: the subordinate clause, called the ''antecedent'' (or ''protasis'' or ''if-clause''), which expresses the condition, and the main clause, called the ''consequent'' (or ''apodosis'' or ''then-clause'') expressing the result. To form conditional sentences, languages use a variety of grammatical forms and constructions. The forms of verbs used in the antecedent and consequent are often subject to particular rules as regards their tense, aspect, and mood. Many languages have a specialized type of verb form called the conditional mood – broadly equivalent in meaning to the English "would (do something)" – for use in some types of conditional sentences.

Optative Mood
The optative mood ( or ; abbreviated ) is a grammatical mood that indicates a wish or hope regarding a given action. It is a superset of the cohortative mood and is closely related to the subjunctive mood but is distinct from the desiderative mood. English has no morphological optative, but various constructions impute an optative meaning. Examples of languages with a morphological optative mood are Ancient Greek, Albanian, Armenian, Georgian, Friulian, Kazakh, Kurdish, Navajo, Old Prussian, Old Persian, Sanskrit, Turkish, and Yup'ik. English Although English has no morphological optative, analogous constructions impute an optative meaning, including the use of certain modal verbs: *''May you have a long life!'' *''Would that I were younger.'' Periphrastic constructions include ''if only'' together with a subjunctive complement: *''If only I were rich!'' *''I would sing if only I weren't tone deaf.'' The optative mood can also be expressed elliptically: *''(May) G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperative Mood
The imperative mood is a grammatical mood that forms a command or request. The imperative mood is used to demand or require that an action be performed. It is usually found only in the present tense, second person. They are sometimes called ''directives'', as they include a feature that encodes directive force, and another feature that encodes modality of unrealized interpretation. An example of a verb used in the imperative mood is the English phrase "Go." Such imperatives imply a second-person subject (''you''), but some other languages also have first- and third-person imperatives, with the meaning of "let's (do something)" or "let them (do something)" (the forms may alternatively be called cohortative and jussive). Imperative mood can be denoted by the glossing abbreviation . It is one of the irrealis moods. Formation Imperative mood is often expressed using special conjugated verb forms. Like other finite verb forms, imperatives often inflect for person and nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Questions
In linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, is a closed-ended question whose expected answer is one of two choices, one that provides an affirmative answer to the question versus one that provides a negative answer to the question. Typically, the choices are either "yes" or "no" in English. Yes–no questions present an exclusive disjunction, namely a pair of alternatives of which only one is a felicitous answer. In English, such questions can be formed in both positive and negative forms: * positive yes/no question: "Will you be here tomorrow?" * negative yes/no question: "Won't you be here tomorrow?" Yes–no questions are in contrast with non-polar wh-questions. The latter are also called content questions, and are formed with the five Ws plus an H ("who", "what", "where", "when", "why", "how"). Rather than restricting the range of possible answers to two alternatives, content questions are compatible with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
