Morphology (linguistics) in the context of Null morpheme

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.

In linguistics, grammar is the set of rules for how a natural language is structured, as demonstrated by its speakers or writers. Grammar rules may concern the use of clauses, phrases, and words. The term may also refer to the study of such rules, a subject that includes phonology, morphology, and syntax, together with phonetics, semantics, and pragmatics. There are, broadly speaking, two different ways to study grammar: traditional grammar and theoretical grammar.

Fluency in a particular language variety involves a speaker internalizing these rules, many or most of which are acquired by observing other speakers, as opposed to intentional study or instruction. Much of this internalization occurs during early childhood; learning a language later in life usually involves more direct instruction. The term grammar can also describe the linguistic behaviour of groups of speakers and writers rather than individuals. Differences in scale are important to this meaning: for example, English grammar could describe those rules followed by every one of the language's speakers. At smaller scales, it may refer to rules shared by smaller groups of speakers.

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.

Maltese (Maltese: Malti, also L-Ilsien Malti or Lingwa Maltija) is a Central Semitic language derived from late medieval Sicilian Arabic with Romance superstrata. It is the only Semitic language written in the Latin script. It is spoken by the Maltese people and is a national language of Malta, and is the only official Semitic and Afroasiatic language of the European Union. According to John L. Hayes, it descended from a North African dialect of Colloquial Arabic which was introduced to Malta when the Aghlabids captured it in 869/870 CE. It is also said to have descended from Siculo-Arabic, which developed as a Maghrebi Arabic dialect in the Emirate of Sicily between 831 and 1091. As a result of the Norman invasion of Malta and the subsequent re-Christianisation of the islands, Maltese evolved independently of Classical Arabic in a gradual process of Latinisation. It is therefore exceptional as a variety of historical Arabic that has no diglossic relationship with Classical or Modern Standard Arabic. Maltese is thus classified separately from the 30 varieties constituting the modern Arabic macrolanguage. Maltese is also distinguished from Arabic and other Semitic languages since its morphology has been deeply influenced by Romance languages, namely Italian and Sicilian.

The original Arabic base comprises around one-third of the Maltese vocabulary, especially words that denote basic ideas and the function words, but about half of the vocabulary is derived from standard Italian and Sicilian; and English words make up between 6% and 20% of the vocabulary. A 2016 study shows that, in terms of basic everyday language, speakers of Maltese are able to understand less than a third of what is said to them in Tunisian Arabic and Libyan Arabic, which are Maghrebi Arabic dialects related to Siculo-Arabic, whereas speakers of Tunisian Arabic and Libyan Arabic are able to understand about 40% of what is said to them in Maltese. This reported level of asymmetric intelligibility is considerably lower than the mutual intelligibility found between mainstream varieties of Arabic.

Romansh (/roʊˈmænʃ, roʊˈmɑːnʃ/ roh-MA(H)NSH; sometimes also spelled Romansch and Rumantsch) is a Romance language of the Gallo-Romance and/or Rhaeto-Romance branch of languages spoken predominantly in the Swiss canton of the Grisons (Graubünden). Romansh has been recognized as a national language of Switzerland since 1938, and as an official language in correspondence with Romansh-speaking citizens since 1996, along with German, French, and Italian. It also has official status in the canton of the Grisons alongside German and Italian and is used as the medium of instruction in schools in Romansh-speaking areas. It is sometimes grouped by linguists with Ladin and Friulian as the Rhaeto-Romance languages, though this is disputed.

Romansh is one of the descendant languages of the spoken Latin language of the Roman Empire, which by the 5th century AD replaced the Celtic and Raetic languages previously spoken in the area. Romansh retains a small number of words from these languages. Romansh has also been strongly influenced by German in vocabulary and morphosyntax. The language gradually retreated to its current area over the centuries, being replaced in other areas by Alemannic and Bavarian dialects. The earliest writing identified as Romansh dates from the 10th or 11th century, although major works did not appear until the 16th century, when several regional written varieties began to develop. During the 19th century the area where the language was spoken declined due to the industrialization of Switzerland, but the Romansh speakers had a literary revival and started a language movement dedicated to halting the decline of their language.

Etymology (/ˌɛtɪˈmɒlədʒi/ ET-ih-MOL-ə-jee) is the study of the origin and evolution of words—including their constituent units of sound and meaning—across time. In the 21st century a subfield within linguistics, etymology has become a more rigorously scientific study. Most directly tied to historical linguistics, philology, and semiotics, it additionally draws upon comparative semantics, morphology, pragmatics, and phonetics in order to attempt a comprehensive and chronological catalogue of all meanings and changes that a word (and its related parts) carries throughout its history. The origin of any particular word is also known as its etymology.

For languages with a long written history, etymologists make use of texts, particularly texts about the language itself, to gather knowledge about how words were used during earlier periods, how they developed in meaning and form, or when and how they entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct information about forms that are too old for any direct information to be available. By analyzing related languages with a technique known as the comparative method, linguists can make inferences about their shared parent language and its vocabulary. In this way, word roots in many European languages, for example, can be traced back to the origin of the Indo-European language family.

The morphology of the Welsh language shows many characteristics perhaps unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs conjugate for person, tense and mood with affirmative, interrogative and negative conjugations of some verbs. A majority of prepositions inflect for person and number. There are few case inflections in Literary Welsh, being confined to certain pronouns.

Modern Welsh can be written in two varieties – Colloquial Welsh or Literary Welsh. The grammar described on this article is for Literary Welsh.

The morphology of the Welsh language has many characteristics likely to be unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs inflect for person, number, tense, and mood, with affirmative, interrogative, and negative conjugations of some verbs. There is no case inflection in Modern Welsh.

Modern Welsh can be written, and spoken, in several levels of formality, for example colloquial or literary, as well as different dialects. The grammar described in this article is for Colloquial Welsh, which is used for speech and informal writing. Literary Welsh is closer to the form of Welsh used in William Morgan's 1588 translation of the Bible and can be seen in formal writing. It does not reflect the spoken language presented here.

In linguistic morphology, inflection (less commonly, inflexion) is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, while the inflection of nouns, adjectives, adverbs, etc. can be called declension.

An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ducam, meaning "I will lead", includes the suffix -am, expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). The use of this suffix is an inflection. In contrast, in the English clause "I will lead", the word lead is not inflected for any of person, number, or tense; it is simply the bare form of a verb. The inflected form of a word often contains both one or more free morphemes (a unit of meaning which can stand by itself as a word), and one or more bound morphemes (a unit of meaning which cannot stand alone as a word). For example, the English word cars is a noun that is inflected for number, specifically to express the plural; the content morpheme car is unbound because it could stand alone as a word, while the suffix -s is bound because it cannot stand alone as a word. These two morphemes together form the inflected word cars.

Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language. In other words, it is how human beings gain the ability to be aware of language, to understand it, and to produce and use words and sentences to communicate.

Language acquisition involves structures, rules, and representation. The capacity to successfully use language requires human beings to acquire a range of tools, including phonology, morphology, syntax, semantics, and an extensive vocabulary. Language can be vocalized as in speech, or manual as in sign. Human language capacity is represented in the brain. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Evidence suggests that every individual has three recursive mechanisms that allow sentences to go indeterminately. These three mechanisms are: relativization, complementation and coordination.

In linguistics, reduplication is a morphological process in which the root or stem of a word, part of that, or the whole word is repeated exactly or with a slight change.

The classic observation on the semantics of reduplication is Edward Sapir's: "Generally employed, with self-evident symbolism, to indicate such concepts as distribution, plurality, repetition, customary activity, increase of size, added intensity, continuance." It is used in inflections to convey a grammatical function, such as plurality or intensification, and in lexical derivation to create new words. It is often used when a speaker adopts a tone more expressive or figurative than ordinary speech and is also often, but not exclusively, iconic in meaning. It is found in a wide range of languages and language groups, though its level of linguistic productivity varies. Examples can be found in language as old as Sumerian, where it was used in forming some color terms, e.g. babbar "white", kukku "black".
