Clinical linguistics is the branch of linguistics that applies linguistic concepts and theories to the study of language disorders. As the name suggests, clinical linguistics is a dual-facing discipline. Although the conceptual roots of this field are in linguistics, its domain of application is the vast array of clinical disorders that may compromise the use and understanding of language. Both dimensions of clinical linguistics can be addressed through an examination of specific linguistic deficits in individuals with neurodevelopmental disorders, craniofacial anomalies, adult-onset neurological impairments, psychiatric disorders, and neurodegenerative disorders. Clinical linguists are interested in the full range of linguistic deficits in these conditions, including phonetic deficits of children with cleft lip and palate, morphosyntactic errors in children with specific language impairment, and pragmatic language impairments in adults with schizophrenia.
Like many applied disciplines in linguistics, clinical linguistics sits at the intersection of a number of areas. The relationship of clinical linguistics to the study of communication disorders and to speech-language pathology (speech and language therapy in the United Kingdom) are two particularly important points of intersection. Speech-language pathology is the area of clinical practice that assesses and treats children and adults with communication disorders. All language disorders restrict an individual’s ability to communicate freely with others in a range of contexts and settings. So language disorders are first and foremost communication disorders. To understand language disorders, it is useful to think of them in terms of points of breakdown on a communication cycle that tracks the progress of a linguistic utterance from its conception in the mind of a speaker to its comprehension by a hearer. This cycle permits the introduction of a number of important distinctions in language pathology, such as the distinction between a receptive and an expressive language disorder, and between a developmental and an acquired language disorder. The cycle is also a useful model with which to conceptualize a range of communication disorders other than language disorders. These other disorders, which include hearing, voice, and fluency disorders, are also relevant to clinical linguistics.
Clinical linguistics draws on the conceptual resources of the full range of linguistic disciplines to describe and explain language disorders. These disciplines include phonetics, phonology, morphology, syntax, semantics, pragmatics, and discourse. Each of these linguistic disciplines contributes concepts and theories that can shed light on the nature of language disorder. A wide range of tools and approaches are used by clinical linguists and speech-language pathologists to assess, diagnose, and treat language disorders. They include the use of standardized and norm-referenced tests, communication checklists and profiles (some administered by clinicians, others by parents, teachers, and caregivers), and qualitative methods such as conversation analysis and discourse analysis. Finally, clinical linguists can contribute to debates about the nosology of language disorders. In order to do so, however, they must have an understanding of the place of language disorders in internationally recognized classification systems such as the 2013 Diagnostic and Statistical Manual of Mental Disorders (DSM-5) of the American Psychiatric Association.
Conversation analysis is an approach to the study of social interaction and talk-in-interaction that, although rooted in the sociological study of everyday life, has exerted significant influence across the humanities and social sciences including linguistics. Drawing on recordings (both audio and video) naturalistic interaction (unscripted, non-elicited, etc.) conversation analysts attempt to describe the stable practices and underlying normative organizations of interaction by moving back and forth between the close study of singular instances and the analysis of patterns exhibited across collections of cases. Four important domains of research within conversation analysis are turn-taking, repair, action formation and ascription, and action sequencing.

Deictic expressions, like English ‘this, that, here, and there’ occur in all known human languages. They are typically used to individuate objects in the immediate context in which they are uttered, by pointing at them so as to direct attention to them. The object, or demonstratum is singled out as a focus, and a successful act of deictic reference is one that results in the Speaker (Spr) and Addressee (Adr) attending to the same referential object. Thus,
(1)A:Oh, there’sthat guy again (pointing)B:Oh yeah, now I see him (fixing gaze on the guy)
(2)A:I’ll have that one over there (pointing to a dessert on a tray)B:This? (touching pastry with tongs)A:yeah, that looks greatB:Here ya’ go (handing pastry to customer)
In an exchange like (1), A’s utterance spotlights the individual guy, directing B’s attention to him, and B’s response (both verbal and ocular) displays that he has recognized him. In (2) A’s utterance individuates one pastry among several, B’s response makes sure he’s attending to the right one, A reconfirms and B completes by presenting the pastry to him. If we compare the two examples, it is clear that the underscored deictics can pick out or present individuals without describing them. In a similar way, “I, you, he/she, we, now, (back) then,” and their analogues are all used to pick out individuals (persons, objects, or time frames), apparently without describing them. As a corollary of this semantic paucity, individual deictics vary extremely widely in the kinds of object they may properly denote: ‘here’ can denote anything from the tip of your nose to planet Earth, and ‘this’ can denote anything from a pastry to an upcoming day (this Tuesday). Under the same circumstance, ‘this’ and ‘that’ can refer appropriately to the same object, depending upon who is speaking, as in (2). How can forms that are so abstract and variable over contexts be so specific and rigid in a given context? On what parameters do deictics and deictic systems in human languages vary, and how do they relate to grammar and semantics more generally?
Gender is a grammatical feature, in a family with person, number, and case. In the languages that have grammatical gender—according to a representative typological sample, almost half of the languages in the world—it is a property that separates nouns into classes. These classes are often meaningful and often linked to biological sex, which is why many languages are said to have a “masculine” and a “feminine” gender. A typical example is Italian, which has masculine words for male persons (il bambino “the.
Across the languages of the world, gender systems vary widely. They differ in the number of classes, in the underlying assignment rules, and in how and where gender is marked. Since agreement is a definitional property, gender is generally absent in isolating languages as well as in young languages with little bound morphology, including sign languages. Therefore, gender is considered a mature phenomenon in language.
Gender interacts in various ways with other grammatical features. For example, it may be limited to the singular number or the third person, and it may be crosscut by case distinctions. These and other interrelations can complicate the task of figuring out a gender system in first or second language acquisition. Yet, children master gender early, making use of a broad variety of cues. By contrast, gender is famously difficult for second-language learners. This is especially true for adults and for learners whose first language does not have a gender system. Nevertheless, tests show that even for this group, native-like competence is possible to attain.
Interest in the linguistics of humor is widespread and dates since classical times. Several theoretical models have been proposed to describe and explain the function of humor in language. The most widely adopted one, the semantic-script theory of humor, was presented by Victor Raskin, in 1985. Its expansion, to incorporate a broader gamut of information, is known as the General Theory of Verbal Humor. Other approaches are emerging, especially in cognitive and corpus linguistics. Within applied linguistics, the predominant approach is analysis of conversation and discourse, with a focus on the disparate functions of humor in conversation. Speakers may use humor pro-socially, to build in-group solidarity, or anti-socially, to exclude and denigrate the targets of the humor. Most of the research has focused on how humor is co-constructed and used among friends, and how speakers support it. Increasingly, corpus-supported research is beginning to reshape the field, introducing quantitative concerns, as well as multimodal data and analyses. Overall, the linguistics of humor is a dynamic and rapidly changing field.

About 7,000 languages are spoken around the world today. The actual number depends on where the line is drawn between language and dialect—an arbitrary decision, because languages are always in flux. But specialists applying a reasonably uniform criterion across the globe count well over 2,000 languages in Asia and Africa, while Europe has just shy of 300. In between are the Pacific region, with over 1,300 languages, and the Americas, with just over 1,000. Languages spoken natively by over a million speakers number around 250, but the vast majority have very few speakers. Something like half are thought likely to disappear over the next few decades, as speakers of endangered languages turn to more widely spoken ones.
The languages of the world are grouped into perhaps 430 language families, based on their origin, as determined by comparing similarities among languages and deducing how they evolved from earlier ones. As with languages, there’s quite a lot of disagreement about the number of language families, reflecting our meager knowledge of many present-day languages and even sparser knowledge of their history. The figure 430 comes from Glottolog.org, which actually lists them all. While the world’s language families may well go back to a smaller number of original languages, even to a single mother tongue, scholars disagree on how far back current methods permit us to trace the history of languages.
While it is normal for languages to borrow from other languages, occasionally a totally new language is created by mixing elements of two distinct languages to such a degree that we would not want to identify one of the source languages as the mother tongue. This is what led to the development of Media Lengua, a language of Ecuador formed through contact among speakers of Spanish and speakers of Quechua. In this language, practically all the word stems are from Spanish, while all of the endings are from Quechua. Just a handful of languages have come into being in this way, but less extreme forms of language mixture have resulted in over a hundred pidgins and creoles currently spoken in many parts of the world. Most arose during Europe’s colonial era, when European colonists used their language to communicate with local inhabitants, who in turn blended vocabulary from the European language with grammar largely from their native language.
Also among the languages of the world are about 300 sign languages used mainly in communicating among and with the deaf. The structure of sign languages typically has little historical connection to the structure of nearby spoken languages.
Some languages have been constructed expressly, often by a single individual, to meet communication demands among speakers with no common language. Esperanto, designed to serve as a universal language and used as a second language by some two million, according to some estimates, is the prime example, but it is only one among several hundred would-be international auxiliary languages.
This essay surveys the languages of the world continent by continent, ending with descriptions of sign languages and of pidgins and creoles. A set of references grouped by section appears at the very end. The main source for data on language classification, numbers of languages, and speakers is the 19th edition of Ethnologue (see Resources), except where a different source is cited.
Pidgin languages sometimes form in contact situations where a means of communication is urgently needed between groups lacking a common code. They are typically less elaborate than any of the languages involved in their formation, and in comparison to those, reduction characterizes all linguistic levels.
The process is relatively uncommon, and the life span of pidgins is usually short – most disappear when the contact situation changes, or when another medium of intergroup communication becomes available. In some rare cases, however, they expand (both socially and structurally), and may even nativize, i. e. become mother tongues to their speakers (when they may be re-labelled “creoles”).
Pidgins are severely understudied, and while they are often mentioned as precursors to creoles, few linguists have shown a serious interest in them. As a result, many generalizations have been based on extremely limited amounts of data or even on intuition. Some frequently occurring ones is that pidginization is a case of second language acquisition, that power and prestige are important factors, and that most structures are derived from the input languages. My work with pidgins has led me to believe the opposite to be true in these cases: pidgins form through a trial-and-error process, where anything that is understood by the other party is sanctioned, this process is one of collaborative language creation (rather than one involving one group of teachers and one group of learners), and much of what finds its way in the resultant contact language do so independently of what the creators spoke prior to their encounter.
As for theoretical implications, pidgins may shed light on which features in traditional languages are necessary for communication, and which are superfluous from the point of view of pure information transmission.

Taking a sociolinguistic approach to prescriptivism in English usage, this article presents different methods by which highly frequent usage problems can be analyzed as to their current acceptability. These methods comprise different ways of studying a selected number of well-known items—try and/try to, the placement of only, the split infinitive and the dangling participle—focusing on their treatment in British and American usage guides from the beginning of the prescriptive tradition onward, combined with the application of special elicitation techniques to probe the views of informants. Such a multi-modal approach represents a distinct improvement from earlier attempts at presenting targeted groups of informants with attitude surveys only. By studying representative samples of British and American usage guides, the article shows that attitudes became more lenient across time (though not for all usage problems analyzed), with the sociolinguistic variable age playing an important role in the process, but also that instead of usage guides becoming more descriptive in the course of the history of the tradition, today in effect two trends can be distinguished in the type of usage advice given. While one trend indeed shows an increasingly descriptive approach to the items treated, a continuing proscriptive approach characterizes usage guides published down to the beginning of the 21st century.
In the linguistic literature, the term theme has several interpretations, one of which relates to discourse analysis and two others to sentence structure. In a more general (or global) sense, one may speak about the theme or topic (or topics) of a text (or discourse), that is, to analyze relations going beyond the sentence boundary and try to identify some characteristic subject(s) for the text (discourse) as a whole. This analysis is mostly a matter of the domain of information retrieval and only partially takes into account linguistically based considerations. The main linguistically based usage of the term theme concerns relations within the sentence. Theme is understood to be one of the (syntactico-) semantic relations and is used as the label of one of the arguments of the verb; the whole network of these relations is called thematic relations or roles (or, in the terminology of Chomskyan generative theory, theta roles and theta grids). Alternatively, from the point of view of the communicative function of the language reflected in the information structure of the sentence, the theme (or topic) of a sentence is distinguished from the rest of it (rheme, or focus, as the case may be) and attention is paid to the semantic consequences of the dichotomy (especially in relation to presuppositions and negation) and its realization (morphological, syntactic, prosodic) in the surface shape of the sentence. In some approaches to morphosyntactic analysis the term theme is also used referring to the part of the word to which inflections are added, especially composed of the root and an added vowel.
