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,
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?
Evaluative morphology is a field of linguistic studies that deals with the formation of diminutives, augmentatives, pejoratives, and amelioratives. Actually, evaluative constructions cross the boundaries of morphology, and are sometimes realized by formal strategies that cannot be numbered among word formation processes. Nevertheless, morphology plays a dominant role in the formation of evaluatives. The first attempt to draw an exhaustive account of this set of complex forms is found in the 1984 work Generative Morphology, by Sergio Scalise, who made the hypothesis that evaluatives represent a separate block of rules between inflection and derivation. This hypothesis is based on the fact that evaluatives show some properties that are derivational, others that are inflectional, and some specific properties that are neither derivational nor inflectional. After Scalise’s proposal, almost all scholars have tried to answer the question concerning the place of evaluative rules within the morphological component. What data reveal is that, in a cross-linguistic perspective, evaluatives display a uniform behavior from a semantic and functional point of view, but exhibit a wide range of formal properties. In other words, functional identity does not imply formal identity; consequently, we can expect that constructions performing the same function display different formal properties in different languages. So, if evaluatives are undoubtedly derivational in most Indo-European languages (even if they cannot be considered a typical example of derivation), they are certainly quite close to inflection in some Bantu languages. This means that the question about the place of evaluatives within the morphological component probably is not as crucial as scholars have thought, and that other issues, sometimes neglected in the literature, deserve the same attention. Among them, the role of pragmatics in the description of evaluatives is no doubt central. According to Dressler and Merlini Barbaresi, in their 1994 work, Morphopragmatics: Diminutives and Intensifiers in Italian, German and Other Languages, evaluative constructions are the more typical instantiation of morphopragmatics, which is “defined as the area of general pragmatic meanings of morphological rules, that is of the regular pragmatic effects produced when moving from the input to the output of a morphological rule.” Evaluatives include “a pragmatic variable which cannot be suppressed in the description of [their] meaning.” Another central issue in studies on evaluative morphology is the wide set of semantic nuances that usually accompany diminutives, augmentatives, pejoratives, and amelioratives. For example, a diminutive form can occasionally assume a value that is attenuative, singulative, partitive, appreciative, affectionate, etc. This cluster of semantic values has often increased the idea that evaluatives are irregular in nature and that they irremediably avoid any generalization. Dan Jurafsky showed, in 1996, that these different meanings are often the outcome of regular and cross-linguistically recurrent semantic processes, both in a synchronic and in a diachronic perspective.
While both pragmatic theory and experimental investigations of language using psycholinguistic methods have been well-established subfields in the language sciences for a long time, the field of Experimental Pragmatics, where such methods are applied to pragmatic phenomena, has only fully taken shape since the early 2000s. By now, however, it has become a major and lively area of ongoing research, with dedicated conferences, workshops, and collaborative grant projects, bringing together researchers with linguistic, psychological, and computational approaches across disciplines. Its scope includes virtually all meaning-related phenomena in natural language comprehension and production, with a particular focus on what inferences utterances give rise to that go beyond what is literally expressed by the linguistic material.
One general area that has been explored in great depth consists of investigations of various ‘ingredients’ of meaning. A major aim has been to develop experimental methodologies to help classify various aspects of meaning, such as implicatures and presuppositions as compared to basic truth-conditional meaning, and to capture their properties more thoroughly using more extensive empirical data. The study of scalar implicatures (e.g., the inference that some but not all students left based on the sentence Some students left) has served as a catalyst of sorts in this area, and they constitute one of the most well-studied phenomena in Experimental Pragmatics to date. But much recent work has expanded the general approach to other aspects of meaning, including presuppositions and conventional implicatures, but also other aspects of nonliteral meaning, such as irony, metonymy, and metaphors.
The study of reference constitutes another core area of research in Experimental Pragmatics, and has a more extensive history of precursors in psycholinguistics proper. Reference resolution commonly requires drawing inferences beyond what is conventionally conveyed by the linguistic material at issue as well; the key concern is how comprehenders grasp the referential intentions of a speaker based on the referential expressions used in a given context, as well as how the speaker chooses an appropriate expression in the first place. Pronouns, demonstratives, and definite descriptions are crucial expressions of interest, with special attention to their relation to both intra- and extralinguistic context. Furthermore, one key line of research is concerned with speakers’ and listeners’ capacity to keep track of both their own private perspective and the shared perspective of the interlocutors in actual interaction.
Given the rapid ongoing growth in the field, there is a large number of additional topical areas that cannot all be mentioned here, but the final section of the article briefly mentions further current and future areas of research.
Experimental Semiotics (ES) is a burgeoning new discipline aimed at investigating in the laboratory the development of novel forms of human communication. Conceptually connected to experimental research on language use, ES provides a scientific complement to field studies of spontaneously emerging new languages and studies on the emergence of communication systems among artificial agents.
ES researchers have created quite a few research paradigms to investigate the development of novel forms of human communication. Despite their diversity, these paradigms all rely on the use of semiotic games, that is, games in which people can succeed reliably only after they have developed novel communication systems. Some of these games involve creating novel signs for pre-specified meanings. These games are particularly suitable for studying relatively large communication systems and their structural properties. Other semiotic games involve establishing shared meanings as well as novel signs to communicate about them. These games are typically rather challenging and are particularly suitable for investigating the processes through which novel forms of communication are created.
Considering that ES is a methodological stance rather than a well-defined research theme, researchers have used it to address a greatly heterogeneous set of research questions. Despite this, and despite the recent origins of ES, two of these questions have begun to coalesce into relatively coherent research themes.
The first theme originates from the observation that novel communication systems developed in the laboratory tend to acquire features that are similar to key features of natural language. Most notably, they tend (a) to rely on the use of symbols—that is purely conventional signs—and (b) to adopt a combinatorial design, using a few basic units to express a large number of meanings. ES researchers have begun investigating some of the factors that lead to the acquisition of such features. These investigations suggest two conclusions. The first is that the emergence of symbols depends on the fact that, when repeatedly using non-symbolic signs, people tend to progressively abstract them. The second conclusion is that novel communication systems tend to adopt a combinatorial design more readily when their signs have low degrees of motivation and fade rapidly.
The second research theme originates from the observation that novel communication systems developed in the laboratory tend to begin systematically with motivated—that is non-symbolic—signs. ES investigations of this tendency suggest that it occurs because motivation helps people bootstrap novel forms of communication. Put it another way, these investigations show that it is very difficult for people to bootstrap communication through arbitrary signs.
Game theory provides formal means of representing and explaining action choices in social decision situations where the choices of one participant depend on the choices of another. Game theoretic pragmatics approaches language production and interpretation as a game in this sense. Patterns in language use are explained as optimal, rational, or at least nearly optimal or rational solutions to a communication problem. Three intimately related perspectives on game theoretic pragmatics are sketched here: (i) the evolutionary perspective explains language use as the outcome of some optimization process, (ii) the rationalistic perspective pictures language use as a form of rational decision-making, and (iii) the probabilistic reasoning perspective considers specifically speakers’ and listeners’ beliefs about each other. There are clear commonalities behind these three perspectives, and they may in practice blend into each other.
At the heart of game theoretic pragmatics lies the idea that speaker and listener behavior, when it comes to using a language with a given semantic meaning, are attuned to each other. By focusing on the evolutionary or rationalistic perspective, we can then give a functional account of general patterns in our pragmatic language use. The probabilistic reasoning perspective invites modeling actual speaker and listener behavior, for example, as it shows in quantitative aspects of experimental data.
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.

Meanings are assembled in various ways in a construction-based grammar, and this array can be represented as a continuum of idiomaticity, a gradient of lexical fixity. Constructional meanings are the meanings to be discovered at every point along the idiomaticity continuum. At the leftmost, or ‘fixed,’ extreme of this continuum are frozen idioms, like the salt of the earth and in the know. The set of frozen idioms includes those with idiosyncratic syntactic properties, like the fixed expression by and large (an exceptional pattern of coordination in which a preposition and adjective are conjoined). Other frozen idioms, like the unexceptionable modified noun red herring, feature syntax found elsewhere. At the rightmost, or ‘open’ end of this continuum are fully productive patterns, including the rule that licenses the string Kim blinked, known as the Subject-Predicate construction. Between these two poles are (a) lexically fixed idiomatic expressions, verb-headed and otherwise, with regular inflection, such as chew/chews/chewed the fat; (b) flexible expressions with invariant lexical fillers, including phrasal idioms like spill the beans and the Correlative Conditional, such as the more, the merrier; and (c) specialized syntactic patterns without lexical fillers, like the Conjunctive Conditional (e.g., One more remark like that and you’re out of here). Construction Grammar represents this range of expressions in a uniform way: whether phrasal or lexical, all are modeled as feature structures that specify phonological and morphological structure, meaning, use conditions, and relevant syntactic information (including syntactic category and combinatoric potential).

Politeness comprises linguistic and non-linguistic behavior through which people indicate that they take others’ feelings of how they should be treated into account. Politeness comes into operation through evaluative moments—the interactants’ (or other participants’) assessments of interactional behavior—and it is a key interpersonal interactional phenomenon, due to the fact that it helps people to build up and maintain interpersonal relationships. The operation of politeness involves valences: when people behave in what they perceive as polite in a given situation, they attempt to enactment shared values with others, hence triggering positive emotions. The interactants use valenced categories as a benchmark for their production and evaluation of language and behavior, and valence reflects the participants’ perceived moral order of an interactional context/event, that is, their perceptions of ‘how things should be’ in a given situation. Thus, the examination of politeness reveals information about the broader in-group, social, and cultural values that underlie the productive and evaluative interactional behavior of individuals. As politeness is a social action that consists of both linguistic and non-linguistic elements and that embodies a social practice, the research of politeness also provides insights into the social practices that surround individual language use.
Pragmatics-based research on politeness started in the late 1970s and early 1980s, and has become one of the most popular areas in pragmatics. The field has undergone various methodological and theoretical changes. These include the “first wave” of politeness research, in the course of which researchers either attempted to model politeness across languages and cultures by using universal frameworks, or engaged in culture-specific criticism of such frameworks. In the “second wave” of politeness research, researchers attempted to approach politeness as an individualistic, and often idiosyncratic, interactionally co-constructed phenomenon. A key argument of the second wave is that politeness can only be studied at the micro-level of the individual, and so it may be overambitious to attempt to model this phenomenon across languages and cultures. In the “third wave” of politeness research, scholars attempt to model politeness across languages and cultures, without compromising the endeavour of examining politeness as an interactionally co-constructed phenomenon.
Key phenomena studied in politeness research include, among others, impoliteness, intercultural interaction, cross-cultural similarities and differences of politeness, the gendered characteristics of politeness behavior, and convention and ritual. Politeness research is a multidisciplinary field that is engaged in the examination of a wide variety of data types.
