Morphology (linguistics) in the context of "Grammar"

Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions.

Linguistics encompasses many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal and fundamental nature of language and developing a general theoretical framework for describing it. Applied linguistics seeks to utilize the scientific findings of the study of language for practical purposes, such as developing methods of improving language education and literacy.

The concept of communicative competence, as developed in linguistics, originated in response to perceived inadequacy of the notion of linguistic competence. That is, communicative competence encompasses a language user's grammatical knowledge of syntax, morphology, phonology and the like, but reconceives this knowledge as a functional, social understanding of how and when to use utterances appropriately.

Communicative language teaching is a pedagogical application of communicative competence.

Standard French (in French: le français standard, le français normé, le français neutre 'Neutral French' or le français international 'International French') is an unofficial term for a standard variety of the French language. It is a set of spoken and written formal varieties used by the educated francophones of several nations around the world.

As French is a pluricentric language, Standard French encompasses various linguistic norms (consisting of prescribed usage). The syntax, morphology, and orthography of Standard French are explained in various works on grammar and style such as the Bescherelle, a reference summary of verb conjugations first compiled in the 19th century by Louis-Nicolas Bescherelle from France, and Le Bon Usage written in the 20th century by Belgian grammarian Maurice Grevisse.

A morpheme is any of the smallest meaningful constituents within a linguistic expression and particularly within a word. Many words are themselves standalone morphemes, while other words contain multiple morphemes; in linguistic terminology, this is the distinction, respectively, between free and bound morphemes. The field of linguistic study dedicated to morphemes is called morphology.

In English, inside a word with multiple morphemes, the main morpheme that gives the word its basic meaning is called a root (such as cat inside the word cats), which can be bound or free. Meanwhile, additional bound morphemes, called affixes, may be added before or after the root, like the -s in cats, which indicates plurality but is always bound to a root noun and is not regarded as a word on its own. However, in some languages, including English and Latin, even many roots cannot stand alone; i.e., they are bound morphemes. For instance, the Latin root reg- ('king') must always be suffixed with a case marker: regis, regi, rex (reg+s), etc. The same is true of the English root nat(e) — ultimately inherited from a Latin root meaning "birth, born" — which appears in words like native, nation, nature, innate, and neonate.

A root (also known as a root word or radical) is the core of a word that is irreducible into more meaningful elements. In morphology, a root is a morphologically simple unit which can be left bare or to which a prefix or a suffix can attach. The root word is the primary lexical unit of a word, and of a word family (this root is then called the base word), which carries aspects of semantic content and cannot be reduced into smaller constituents.Content words in nearly all languages contain, and may consist only of, root morphemes. However, sometimes the term "root" is also used to describe the word without its inflectional endings, but with its lexical endings in place. For example, chatters has the inflectional root or lemma chatter, but the lexical root chat. Inflectional roots are often called stems. A root, or a root morpheme, in the stricter sense, is a mono-morphemic stem. An etymon is the root word in a proto-language from which the descendant forms arose.

The traditional definition allows roots to be either free morphemes or bound morphemes. Root morphemes are the building blocks for affixation and compounds. However, in polysynthetic languages with very high levels of inflectional morphology, the term "root" is generally synonymous with "free morpheme". Many languages have a very restricted number of morphemes that can stand alone as a word: Yup'ik, for instance, has no more than two thousand.

In linguistics, definiteness is a semantic feature of noun phrases that distinguishes between referents or senses that are identifiable in a given context (definite noun phrases) and those that are not (indefinite noun phrases). The prototypical definite noun phrase picks out a unique, familiar, specific referent such as the sun or Australia, as opposed to indefinite examples like an idea or some fish.

There is considerable variation in the expression of definiteness across languages, and some languages such as Japanese do not generally mark it, so the same expression can be definite in some contexts and indefinite in others. In other languages, such as English, it is usually marked by the selection of determiner (e.g., the vs. a). Still other languages, such as Danish, mark definiteness morphologically by changing the noun itself (e.g. Danish en mand (a man), manden (the man)).

Proto-Celtic, or Common Celtic, is the reconstructed ancestral proto-language of all known Celtic languages, and a descendant of Proto-Indo-European. It is not attested in writing but has been partly reconstructed through the comparative method. Proto-Celtic is generally thought to have been spoken between 1300 and 800 BC, after which it began to split into different languages. Proto-Celtic is often associated with the Urnfield culture and particularly with the Hallstatt culture. Celtic languages share common features with Italic languages that are not found in other branches of Indo-European, suggesting the possibility of an earlier Italo-Celtic linguistic unity.

Proto-Celtic is currently being reconstructed through the comparative method by relying on later Celtic languages. Though Continental Celtic presents much substantiation for Proto-Celtic phonology, and some for its morphology, recorded material is too scanty to allow a secure reconstruction of syntax, though some complete sentences are recorded in the Continental Gaulish and Celtiberian. So, the main sources for reconstruction come from Insular Celtic languages with the oldest literature found in Old Irish and Middle Welsh, dating back to authors flourishing in the 6th century AD.

In historical linguistics, sister languages are languages that are descended from a common ancestral language. Every language in a language family that descends from the same language as the others is a sister to them.

A commonly given example is of Urdu and Hindi (the standardized registers of the Hindustani language), which are mutually intelligible with each other. Also, the Romance languages, each of which is a continuation of Vulgar Latin. Italian and French (both Romance languages) have about 89% lexical overlap, meaning 89 percent of words share the same characteristics and root origins. Similarly, Spanish and Portuguese also have about 89% lexical overlap. Spanish and Romanian overlap less, about 67%, because while Spanish and Portuguese have undergone Arabic influence, Romanian has undergone many different influences over the years, particularly from the Slavic languages and Greek. Along with a large amount of shared vocabulary, the Romance languages share numerous features of morphology and syntax because they are all continuations of their common ancestor, Latin.
