Lexicology is the branch of linguistics that analyzes the lexicon of a specific language. A word is the smallest meaningful unit of a language that can stand on its own, and is made up of small components called morphemes and even smaller elements known as phonemes, or distinguishing sounds. Lexicology examines every feature of a word – including formation, spelling, origin, usage, and definition.
Systemic functional grammar (SFG) is a form of grammatical description originated by Michael Halliday. It is part of a social semiotic approach to language called systemic functional linguistics. In these two terms, systemic refers to the view of language as "a network of systems, or interrelated sets of options for making meaning"; functional refers to Halliday's view that language is as it is because of what it has evolved to do. Thus, what he refers to as the multidimensional architecture of language "reflects the multidimensional nature of human experience and interpersonal relations."
A syntactic category is a syntactic unit that theories of syntax assume. Word classes, largely corresponding to traditional parts of speech, are syntactic categories. In phrase structure grammars, the phrasal categories are also syntactic categories. Dependency grammars, however, do not acknowledge phrasal categories.
In grammar, a part of speech or part-of-speech is a category of words that have similar grammatical properties. Words that are assigned to the same part of speech generally display similar syntactic behavior, sometimes similar morphological behavior in that they undergo inflection for similar properties and even similar semantic behavior. Commonly listed English parts of speech are noun, verb, adjective, adverb, pronoun, preposition, conjunction, interjection, numeral, article, and determiner.
Historical linguistics, also termed diachronic linguistics, is the scientific study of language change over time. Principal concerns of historical linguistics include:
- to describe and account for observed changes in particular languages
- to reconstruct the pre-history of languages and to determine their relatedness, grouping them into language families
- to develop general theories about how and why language changes
- to describe the history of speech communities
- to study the history of words, i.e. etymology
- to explore the impact of cultural and social factors on language evolution.
In linguistics, function words are words that have little lexical meaning or have ambiguous meaning and express grammatical relationships among other words within a sentence, or specify the attitude or mood of the speaker. They signal the structural relationships that words have to one another and are the glue that holds sentences together. Thus they form important elements in the structures of sentences.
In linguistics, a compound verb or complex predicate is a multi-word compound that functions as a single verb. One component of the compound is a light verb or vector, which carries any inflections, indicating tense, mood, or aspect, but provides only fine shades of meaning. The other, "primary", component is a verb or noun which carries most of the semantics of the compound, and determines its arguments. It is usually in either base or [in Verb + Verb compounds] conjunctive participial form.
In linguistics, productivity is the degree to which speakers of a language use a particular grammatical process, especially in word formation. It compares grammatical processes that are in frequent use to less frequently used ones that tend towards lexicalization. Generally the test of productivity concerns identifying which grammatical forms would be used in the coining of new words: these will tend to only be converted to other forms using productive processes.
In linguistics, a grammatical category or grammatical feature is a property of items within the grammar of a language. Within each category there are two or more possible values, which are normally mutually exclusive. Frequently encountered grammatical categories include:
Principles and parameters is a framework within generative linguistics in which the syntax of a natural language is described in accordance with general principles and specific parameters that for particular languages are either turned on or off. For example, the position of heads in phrases is determined by a parameter. Whether a language is head-initial or head-final is regarded as a parameter which is either on or off for particular languages. Principles and parameters was largely formulated by the linguists Noam Chomsky and Howard Lasnik. Many linguists have worked within this framework, and for a period of time it was considered the dominant form of mainstream generative linguistics.
In linguistics and social sciences, markedness is the state of standing out as nontypical or divergent as opposed to regular or common. In a marked–unmarked relation, one term of an opposition is the broader, dominant one. The dominant default or minimum-effort form is known as unmarked; the other, secondary one is marked. In other words, markedness involves the characterization of a "normal" linguistic unit against one or more of its possible "irregular" forms.
In historical linguistics, grammaticalization is a process of language change by which words representing objects and actions become grammatical markers. Thus it creates new function words from content words, rather than deriving them from existing bound, inflectional constructions. For example, the Old English verb willan 'to want', 'to wish' has become the Modern English auxiliary verb will, which expresses intention or simply futurity. Some concepts are often grammaticalized, while others, such as evidentiality, are not so much.
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
Layering in linguistics refers to one of the five principles by which grammaticalisation can be detected while it is taking place. The others are divergence, specialisation, persistence, and de-categorialisation.
Divergence in linguistics refers to one of the five principles by which grammaticalization can be detected while it is taking place. The other four are: layering, specialisation, persistence, and de-categorialisation.
In linguistics, the term specialization, refers to one of the five principles by which grammaticalization can be detected while it is taking place. The other four principles are: layering, divergence, persistence, and de-categorialization.
De-categorialization in linguistics refers to one of the five principles by which grammaticalization can be detected while it is taking place. The other four are layering, divergence, specialization, and persistence.
Linguistics is the scientific study of language. Modern-day linguistics is considered a science because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language – i.e., the cognitive, the social, the cultural, the psychological, the environmental, the biological, the literary, the grammatical, the paleographical, and the structural.
Wandala, also known as Mandara or Mura', is a language in the Chadic branch of the Afro-Asiatic language family, spoken in Cameroon and Nigeria.
In historical linguistics, subjectification is a language change process in which a linguistic expression acquires meanings that convey the speaker's attitude or viewpoint. An English example is the word while, which, in Middle English, had only the sense of 'at the same time that'. It later acquired the meaning of 'although', indicating a concession on the part of the speaker.
