Subject (grammar)
A subject is one of the two main parts of a Sentence (linguistics), sentence (the other being the Predicate (grammar), predicate, which modifies the subject). For the simple Sentence (linguistics), sentence ''John runs'', ''John'' is the subject, a person or thing about whom the statement is made. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb Agreement (linguistics), agrees (''John is'' but ''John and Mary are''). If there is no verb, as in ''Nicola what an idiot!'', or if the verb has a different subject, as in ''John I can't stand him!'', then 'John' is not considered to be the grammatical subject, but can be described as the ''Topic and comment, topic'' of the sentence. While these definitions apply to simple English sentences, defining the subject is more difficult in more complex sentences and languages. For example, in the sentence ''It is difficult to learn French'', the subject seems to be the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentence (linguistics)
In linguistics and grammar, a sentence is a Expression (linguistics), linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar, it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a Subject (grammar), subject and Predicate (grammar), predicate. In non-functional linguistics it is typically defined as a maximal unit of syntactic structure such as a Constituent_(linguistics), constituent. In functional linguistics, it is defined as a unit of written texts delimited by writing, graphological features such as upper-case letters and markers such as periods, question marks, and exclamation marks. This notion contrasts with a curve, which is delimited by phonologic features such as pitch and loudness and markers such as pauses; and with a clause, which is a sequence of words that represents some process going on throughout time. A sentence can include words grouped meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intransitive Verb
In grammar, an intransitive verb is a verb, aside from an auxiliary verb, whose context does not entail a transitive object. That lack of an object distinguishes intransitive verbs from transitive verbs, which entail one or more objects. Additionally, intransitive verbs are typically considered within a class apart from modal verbs and defective verbs. Examples In the following sentences, verbs are used without a direct object: *"Rivers flow." *"I sneezed." *"My dog ran." *"Water evaporates when it's hot." *"You've grown since I last saw you!" *"I wonder how long it will be until I see you again after I move." The following sentences contain transitive verbs (they entail one or more objects): *"We watched ''a movie'' last night." *"She's making ''promises''." *"When I said that, my sister smacked ''me''." *"Santa gave ''me'' ''a present''." *"He continuously clicked ''his pen'' and it was incredibly annoying to me." Some verbs, called ambitransitive verbs, may entail o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topic (grammar)
In linguistics, the topic, or theme, of a sentence is what is being talked about, and the comment (rheme or focus) is what is being said about the topic. This division into old vs. new content is called information structure. It is generally agreed that clauses are divided into topic vs. comment, but in certain cases the boundary between them depends on which specific grammatical theory is being used to analyze the sentence. The topic of a sentence is distinct from the grammatical subject. The topic is defined by pragmatic considerations, that is, the context that provides meaning. The grammatical subject is defined by syntax. In any given sentence the topic and grammatical subject may be the same, but they need not be. For example, in the sentence "As for the little girl, the dog bit her", the subject is "the dog" but the topic is "the little girl". Topic being what is being talked about and the subject being what is doing the action can, also, be distinct concepts fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raising (syntax)
In linguistics, raising constructions involve the syntactic movement, movement of an argument (linguistics), argument from an embedded or subordinate clause to a matrix or main clause. A raising predicate (grammar), predicate/verb appears with a syntactic argument that is not its semantic argument but rather the semantic argument of an embedded predicate. In other words, the sentence is expressing something about a phrase taken as a whole. For example, in ''they seem to be trying'', ''"to be trying"'' (the predicand of ''trying'') is the subject of ''seem''. English language, English has raising constructions, unlike some other languages. The term ''raising'' has its origins in the Transformational Grammar, transformational analysis of such constructions; the constituent (linguistics), constituent in question is seen as being "raised" from its initial deep structure position, as the subject of the embedded predicate, to its Deep structure and surface structure, surface structure p ...

Predicand
In semantics, a predicand is an argument in an utterance, specifically that of which something is predicated. By extension, in syntax, it is the constituent in a clause typically functioning as the subject. Examples In the most typical cases, the predicand corresponds to the subject of a clause, and the predicate corresponds to a verb phrase (VP) that is the head of the clause. But there are also form-meaning mismatches, where the predicand is not a subject or where the predicate is not the head of the clause. Also, not every utterance has a predicand. When predicates correspond to the head of the clause The typical case involves a predicand corresponding to the subject and a predicate corresponding to a verb phrase that is the head of the clause. Subject predicands Predicands are usually expressed in the utterance, and they are typically the subject. In the English example (1), the predicand is the person being spoken to, which corresponds to the subject ''you.'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument (linguistics)
In linguistics, an argument is an expression that helps complete the meaning of a predicate (grammar), predicate, the latter referring in this context to a main verb and its auxiliaries. In this regard, the ''Complement (linguistics), complement'' is a closely related concept. Most predicates take one, two, or three arguments. A predicate and its arguments form a ''predicate-argument structure''. The discussion of predicates and arguments is associated most with (content) verbs and noun phrases (NPs), although other syntactic category, syntactic categories can also be construed as predicates and as arguments. Arguments must be distinguished from adjunct (grammar), adjuncts. While a predicate needs its arguments to complete its meaning, the adjuncts that appear with a predicate are optional; they are not necessary to complete the meaning of the predicate. Most theories of syntax and semantics acknowledge arguments and adjuncts, although the terminology varies, and the distinction is ...

Dependency Grammar
Dependency grammar (DG) is a class of modern Grammar, grammatical theories that are all based on the dependency relation (as opposed to the ''constituency relation'' of Phrase structure grammar, phrase structure) and that can be traced back primarily to the work of Lucien Tesnière. Dependency is the notion that linguistic units, e.g. words, are connected to each other by directed links. The (finite) verb is taken to be the structural center of clause structure. All other syntactic units (words) are either directly or indirectly connected to the verb in terms of the directed links, which are called ''dependencies''. Dependency grammar differs from phrase structure grammar in that while it can identify phrases it tends to overlook phrasal nodes. A dependency structure is determined by the relation between a word (a Head (linguistics), head) and its dependents. Dependency structures are flatter than phrase structures in part because they lack a finite verb, finite verb phrase constit ...

Predicate Logic
First-order logic, also called predicate logic, predicate calculus, or quantificational logic, is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables. Rather than propositions such as "all humans are mortal", in first-order logic one can have expressions in the form "for all ''x'', if ''x'' is a human, then ''x'' is mortal", where "for all ''x"'' is a quantifier, ''x'' is a variable, and "... ''is a human''" and "... ''is mortal''" are predicates. This distinguishes it from propositional logic, which does not use quantifiers or relations; in this sense, propositional logic is the foundation of first-order logic.

Predicate (grammar)
The term predicate is used in two ways in linguistics and its subfields. The first defines a predicate as everything in a standard declarative sentence except the subject (grammar), subject, and the other defines it as only the main content verb or associated predicative expression of a clause. Thus, by the first definition, the predicate of the sentence ''Frank likes cake'' is ''likes cake'', while by the second definition, it is only the content verb ''likes'', and ''Frank'' and ''cake'' are the argument (linguistics), arguments of this predicate. The conflict between these two definitions can lead to confusion. Syntax Traditional grammar The notion of a predicate in traditional grammar traces back to Aristotelian logic. A predicate is seen as a property that a subject has or is characterized by. A predicate is therefore an expression that can be ''true of'' something. Thus, the expression "is moving" is true of anything that is moving. This classical understanding of pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constituent (linguistics)
In syntactic analysis, a constituent is a word or a group of words that function as a single unit within a hierarchical structure. The constituent structure of sentences is identified using ''tests for constituents''. These tests apply to a portion of a sentence, and the results provide evidence about the constituent structure of the sentence. Many constituents are phrases. A phrase is a sequence of one or more words (in some theories two or more) built around a head lexical item and working as a unit within a sentence. A word sequence is shown to be a phrase/constituent if it exhibits one or more of the behaviors discussed below. The analysis of constituent structure is associated mainly with phrase structure grammars, although dependency grammars also allow sentence structure to be broken down into constituent parts. Tests for constituents in English Tests for constituents are diagnostics used to identify sentence structure. There are numerous tests for constituents that are ...

Phrase Structure Grammar
The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue ( Post canonical systems). Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy: context-sensitive grammars or context-free grammars. In a broader sense, phrase structure grammars are also known as ''constituency grammars''. The defining character of phrase structure grammars is thus their adherence to the constituency relation, as opposed to the dependency relation of dependency grammars. History In 1956, Chomsky wrote, "A phrase-structure grammar is defined by a finite vocabulary (alphabet) Vp, and a finite set Σ of initial strings in Vp, and a finite set F of rules of the form: X → Y, where X and Y are strings in Vp." Constituency relation In linguistics, phrase structure grammars are all those grammars that are based on the constituency relation, as opposed to the dependency relation ...

Aristotle
Aristotle (; 384–322 BC) was an Ancient Greek philosophy, Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum (classical), Lyceum in Athens, he began the wider Aristotelianism, Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira (ancient city), Stagira in northern Greece during the Classical Greece, Classical period. His father, Nicomachus (father of Aristotle), Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato's Platonic Academy, Academy in Athens and remained there until the age of thirty seven (). Shortly after Plato died, Aristotle left Athens and, at the request ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
