Type theory is a regime for classifying objects (including events) into categories called types. It was originally designed in order to overcome problems relating to the foundations of mathematics relating to Russell’s paradox. It has made an immense contribution to the study of logic and computer science and has also played a central role in formal semantics for natural languages since the initial work of Richard Montague building on the typed λ-calculus. More recently, type theories following in the tradition created by Per Martin-Löf have presented an important alternative to Montague’s type theory for semantic analysis. These more modern type theories yield a rich collection of types which take on a role of representing semantic content rather than simply structuring the universe in order to avoid paradoxes.
Throughout the 20th century, structuralist and generative linguists have argued that the study of the language system (langue, competence) must be separated from the study of language use (parole, performance), but this view of language has been called into question by usage-based linguists who have argued that the structure and organization of a speaker’s linguistic knowledge is the product of language use or performance. On this account, language is seen as a dynamic system of fluid categories and flexible constraints that are constantly restructured and reorganized under the pressure of domain-general cognitive processes that are not only involved in the use of language but also in other cognitive phenomena such as vision and (joint) attention. The general goal of usage-based linguistics is to develop a framework for the analysis of the emergence of linguistic structure and meaning.
In order to understand the dynamics of the language system, usage-based linguists study how languages evolve, both in history and language acquisition. One aspect that plays an important role in this approach is frequency of occurrence. As frequency strengthens the representation of linguistic elements in memory, it facilitates the activation and processing of words, categories, and constructions, which in turn can have long-lasting effects on the development and organization of the linguistic system. A second aspect that has been very prominent in the usage-based study of grammar concerns the relationship between lexical and structural knowledge. Since abstract representations of linguistic structure are derived from language users’ experience with concrete linguistic tokens, grammatical patterns are generally associated with particular lexical expressions.
Language is a system that maps meanings to forms, but the mapping is not always one-to-one. Variation means that one meaning corresponds to multiple forms, for example faster ~ more fast. The choice is not uniquely determined by the rules of the language, but is made by the individual at the time of performance (speaking, writing). Such choices abound in human language. They are usually not just a matter of free will, but involve preferences that depend on the context, including the phonological context. Phonological variation is a situation where the choice among expressions is phonologically conditioned, sometimes statistically, sometimes categorically. In this overview, we take a look at three studies of variable vowel harmony in three languages (Finnish, Hungarian, and Tommo So) formulated in three frameworks (Partial Order Optimality Theory, Stochastic Optimality Theory, and Maximum Entropy Grammar). For example, both Finnish and Hungarian have Backness Harmony: vowels must be all [+back] or all [−back] within a single word, with the exception of neutral vowels that are compatible with either. Surprisingly, some stems allow both [+back] and [−back] suffixes in free variation, for example, analyysi-na ~ analyysi-nä ‘analysis-

The subject of this article is vowel harmony. In its prototypical form, this phenomenon involves agreement between all vowels in a word for some phonological property (such as palatality, labiality, height or tongue root position). This agreement is then evidenced by agreement patterns within morphemes and by alternations in vowels when morphemes are combined into complex words, thus creating allomorphic alternations. Agreement involves one or more harmonic features for which vowels form harmonic pairs, such that each vowel has a harmonic counterpart in the other set. I will focus on vowels that fail to alternate, that are thus neutral (either inherently or in a specific context), and that will be either opaque or transparent to the process. We will compare approaches that use underspecification of binary features and approaches that use unary features. For vowel harmony, vowels are either triggers or targets, and for each, specific conditions may apply. Vowel harmony can be bidirectional or unidirectional and can display either a root control pattern or a dominant/recessive pattern.

William Labov (b. 1927) is an American linguist who pioneered the study of variationist sociolinguistics. Born and raised in northern New Jersey, Labov studied English and philosophy at Harvard University (BA, 1948) and worked as an industrial chemist for several years before entering graduate school in linguistics at Columbia University in 1961. He completed his PhD in 1964, under the direction of Uriel Weinreich. He worked at Columbia until 1971, when he joined the faculty of the University of Pennsylvania, where he taught until his retirement in 2014.
Labov’s influence on the field began with research he conducted in graduate school. His study of changing pronunciations on Martha’s Vineyard, the subject of his master’s thesis, introduced a method for observing sound change in progress and broke with tradition by exploring social motivations for linguistic innovations. For his PhD dissertation, Labov carried out a study of dialect patterns on the Lower East Side of New York City. Using a systematic, quantitative methodology, he demonstrated that linguistic variation is socially stratified, such that the use of pronunciation features (e.g., dropping of post-vocalic /r/) correlates with social class, ethnicity, etc. in regular patterns. Labov’s early research was greatly influential and inspired many scholars to carry out similar projects in other communities. The paradigm came to be known as variationist sociolinguistics.
Much of Labov’s scholarship seeks to advance our understanding of language change. Historical linguists traditionally study completed linguistic changes, often long after they occurred, but Labov developed a method for examining active changes through a quantitative comparison of speakers representing several generations. This approach produces a new perspective on the change process by revealing intermediate stages. Labov has brought insights from this research to bear on theoretical debates within historical linguistics and the field more broadly. His work in this area has also documented many active sound changes in American English. Among these changes are innovations underway in particular dialects, such as the vowel changes in Philadelphia, as well as broader regional patterns, such as the Northern Cities Shift heard in the Great Lakes states.
Throughout his career, social justice concerns have fueled Labov’s research. He has sought to demonstrate that the speech of stigmatized groups is as systematic and rule-governed as any other. He led a pioneering study in Harlem in the late 1960s that shone new light on African American English, demonstrating, for example, that grammatical usages like the deletion of the copula (e.g., He fast) are subject to regular constraints. Labov has served as an expert witness in court and before the U.S. Congress to share insights from his study of African American English. He has also worked to promote literacy for speakers of non-standard dialects, carrying out research on reading and developing material for the teaching of reading to these populations.
Speakers of most languages comprehend and produce a very large number of morphologically complex words. But how? There is a tension between two facts. First, speakers can comprehend and produce novel words, which they have never experienced and therefore could not have stored in memory. For example, English speakers readily generate the plural form of wug. These novel words often look like they are composed of recognizable parts, such as the plural marker -s. Second, speakers also comprehend and produce many words that cannot be straightforwardly decomposed into parts, such as bought or brunch. Morphology is the paradigm example of a quasi-regular domain, full of only partially productive, exception-ridden patterns, many of which nonetheless appear to be learned and used by speakers and listeners. Quasi-regularity has made morphology a fruitful testing ground for alternative views of how the mind works.
Every major approach to the nature of the mind has attempted to tackle morphological processing. These approaches range from symbolic rule-based approaches to connectionist networks of simple neuron-like processing units to clouds of richly specified holistic exemplars. They vary in their assumptions about the nature of mental representations; particularly, those comprising long-term memory of language. They also vary in the computations that the mind is thought to perform; including the computations that are performed by a speaker attempting to produce or comprehend a word. In challenging all major approaches to cognition with its intricate patterns, morphology continues to provide a valuable window onto the nature of the mind.

English clearly is the world’s most widely used language in the early 21st century: the language of formal and other interactions in very many countries, the main tool of globalization, and the default choice for transnational communication. Initially, the expansion of the British Empire, beginning in the 17th century and driven by various motives for colonization, brought it to all continents: North America and the Caribbean, the southern hemisphere (including Australia, New Zealand, South Africa, and other territories), and also Asia, Africa, and the Pacific region. In contact with indigenous languages new, increasingly stable and localized varieties of English with properties and functions of their own have grown in many countries. These varieties have come to be summarily labeled as “World Englishes,” and a new subdiscipline in linguistics has emerged since the 1980s investigating their features and conditions of use. They have conventionally been classified according to their status in specific countries and territories, as native, second, or foreign languages, respectively, and several theoretical models have been proposed to account for their status, developments, and mutual relationships. Vibrant changes of the recent past, broadly associated with a sociolinguistics of globalization and increasing superdiversity, have continued to push the dissemination of English to new contexts, both socially and individually, and a “post-varieties approach” is now being envisaged.
A wide range of facts and issues can be discussed and investigated when addressing World Englishes. The basic perspective, obviously, concerns the sociohistorical diffusion of the language: Who brought English to which territories, when, and why? And how has the language been transformed in different places? It has been argued convincingly (in the “Dynamic Model” of the evolution of Postcolonial Englishes) that despite all geographical, historical, and social differences, amazing similarities in the emergence of these new varieties, grounded in principles of sociolinguistic accommodation and identity transformations, can be identified. In all contexts and territories, contact with local and other languages has been determinative, usually via the process of second-language acquisition of English by indigenous people. Language policies and their implementation by means of strategies of language pedagogy have played a major role, and all of this is shaped decisively by linguistic attitudes—the question of what speakers and authorities believe about such emerging varieties and their relationship to norms of correctness. Also, specific structural patterns and types of linguistic phenomena can be observed in all these varieties on all levels of language organization.
Consequently, the notion of “English” today needs to be retuned from thinking of it as a single, monolithic entity, a linguistic “standard” and a reference system, to understanding it as a set of related, structurally overlapping, but also distinct varieties, the products of a fundamental “glocalization” process with variable, context-dependent outcomes.

Zapotecan languages belong to the Otomanguean stock and consist of two major subgroups: Zapotec and Chatino. They are primarily spoken in Oaxaca, Mexico, and elsewhere in diaspora, particularly in California but also in other parts of the United States and Mexico. Zapotecan languages are spoken in a contiguous area and although all are related genetically, many languages exist in regional diffusion zones such that new changes spread areally. Similarly, individual Zapotecan “languages” often consist of dialect continua.
Zapotecan languages are tonal and also have contrastive phonation types, such as a contrast between modal (V), checked (VɁ), and rearticulated (VɁV) vowels. Some Valley Zapotec languages also have breathy voice, partially due to contact with Mixe. Vowel nasalization is a prominent feature of Chatino and a marginal feature of some Zapotec languages. Consonants usually fall into two contrastive series in Zapotec, commonly termed “fortis” and “lenis,” though the phonetic realizations of these vary from language to language. The historical loss of unstressed vowels is common in many Zapotecan languages, though there are individual Zapotec and Chatino languages that retain them. A stress shift from the final syllable (retained in Chatino) to the first (usually penultimate) syllable of the root (in Zapotec) makes the languages with vowel loss more dissimilar from each other, since a different syllable survives in Chatino versus Zapotec.
Zapotecan languages are head-initial languages with VSO order and are typically head-marking. Common morphology includes pre-posed TAM markers and post-posed person markers on the verb, and derivational prefixes on nouns. An emergent class of prepositions is developing out of what were historically relational nouns. Stative forms of verbs are more common than true adjectives, while numerals have many verbal properties.
Like other Meso-American languages, Zapotecan languages are currently experiencing both a golden age and a moment of unprecedented peril. There is an ever-increasing number of linguists who are native speakers of these languages, and the community of language activists, including students and educators, is growing stronger in Oaxaca and Mexico at large, and indeed worldwide, including where Zapotecan languages are spoken by immigrants. At the same time, the intense political and socioeconomic pressure on communities to shift to Spanish is greater than ever before, and the number of communities where children speak Zapotecan languages is ever shrinking. Children in communities where children speak Zapotecan languages at home are often chastised for doing so in school, which poses a continual threat. Zapotecan languages historically have been in contact with other Meso-American languages such as Nahuatl, Mixtec, Chontal, Mixe, Huave and Chinantec, among others. Today the vast majority of speakers of Zapotecan languages are at least bilingual in their language and Spanish, and many also speak English and/or other Meso-American languages. Zapotecan languages mostly show lexical borrowings from these other languages, and occasional grammatical borrowings. Regional varieties of Spanish show a Zapotecan substrate with numerous calques and interference on every level of the language from phonetics to pragmatics.

Zero or null morphology refers to morphological units that are devoid of phonological content. Whether such entities should be postulated is one of the most controversial issues in morphological theory, with disagreements in how the concept should be delimited, what would count as an instance of zero morphology inside a particular theory, and whether such objects should be allowed even as mere analytical instruments.
With respect to the first problem, given that zero morphology is a hypothesis that comes from certain analyses, delimiting what counts as a zero morpheme is not a trivial matter. The concept must be carefully differentiated from others that intuitively also involve situations where there is no overt morphological marking: cumulative morphology, phonological deletion, etc.
About the second issue, what counts as null can also depend on the specific theories where the proposal is made. In the strict sense, zero morphology involves a complete morphosyntactic representation that is associated to zero phonological content, but there are other notions of zero morphology that differ from the one discussed here, such as absolute absence of morphological expression, in addition to specific theory-internal interpretations of what counts as null. Thus, it is also important to consider the different ways in which something can be morphologically silent.
Finally, with respect to the third side of the debate, arguments are made for and against zero morphology, notably from the perspectives of falsifiability, acquisition, and psycholinguistics. Of particular impact is the question of which properties a theory should have in order to block the possibility that zero morphology exists, and conversely the properties that theories that accept zero morphology associate to null morphemes.
An important ingredient in this debate has to do with two empirical domains: zero derivation and paradigmatic uniformity. Ultimately, the plausibility that zero morphemes exist or not depends on the success at accounting for these two empirical patterns in a better way than theories that ban zero morphology.
