Phonological learnability deals with the formal properties of phonological languages and grammars, which are combined with algorithms that attempt to learn the language-specific aspects of those grammars. The classical learning task can be outlined as follows: Beginning at a predetermined initial state, the learner is exposed to positive evidence of legal strings and structures from the target language, and its goal is to reach a predetermined end state, where the grammar will produce or accept all and only the target language’s strings and structures. In addition, a phonological learner must also acquire a set of language-specific representations for morphemes, words and so on—and in many cases, the grammar and the representations must be acquired at the same time.
Phonological learnability research seeks to determine how the architecture of the grammar, and the workings of an associated learning algorithm, influence success in completing this learning task, i.e., in reaching the end-state grammar. One basic question is about convergence: Is the learning algorithm guaranteed to converge on an end-state grammar, or will it never stabilize? Is there a class of initial states, or a kind of learning data (evidence), which can prevent a learner from converging? Next is the question of success: Assuming the algorithm will reach an end state, will it match the target? In particular, will the learner ever acquire a grammar that deems grammatical a superset of the target language’s legal outputs? How can the learner avoid such superset end-state traps? Are learning biases advantageous or even crucial to success?
In assessing phonological learnability, the analysist also has many differences between potential learning algorithms to consider. At the core of any algorithm is its update rule, meaning its method(s) of changing the current grammar on the basis of evidence. Other key aspects of an algorithm include how it is triggered to learn, how it processes and/or stores the errors that it makes, and how it responds to noise or variability in the learning data. Ultimately, the choice of algorithm is also tied to the type of phonological grammar being learned, i.e., whether the generalizations being learned are couched within rules, features, parameters, constraints, rankings, and/or weightings.

The words and word-parts children acquire at different stages offer insights into how the mental lexicon might be organized. Children first identify ‘words,’ recurring sequences of sounds, in the speech stream, attach some meaning to them, and, later, analyze such words further into parts, namely stems and affixes. These are the elements they store in memory in order to recognize them on subsequent occasions. They also serve as target models when children try to produce those words themselves. When they coin words, they make use of bare stems, combine certain stems with each other, and sometimes add affixes as well. The options they choose depend on how much they need to add to coin a new word, which familiar elements they can draw on, and how productive that option is in the language. Children’s uses of stems and affixes in coining new words also reveal that they must be relying on one representation in comprehension and a different representation in production. For comprehension, they need to store information about the acoustic properties of a word, taking into account different occasions, different speakers, and different dialects, not to mention second-language speakers. For production, they need to work out which articulatory plan to follow in order to reproduce the target word. And they take time to get their production of a word aligned with the representation they have stored for comprehension. In fact, there is a general asymmetry here, with comprehension being ahead of production for children, and also being far more extensive than production, for both children and adults. Finally, as children add more words to their repertoires, they organize and reorganize their vocabulary into semantic domains. In doing this, they make use of pragmatic directions from adults that help them link related words through a variety of semantic relations.
The central goal of the Lexical Semantic Framework (LSF) is to characterize the meaning of simple lexemes and affixes and to show how these meanings can be integrated in the creation of complex words. LSF offers a systematic treatment of issues that figure prominently in the study of word formation, such as the polysemy question, the multiple-affix question, the zero-derivation question, and the form and meaning mismatches question.
LSF has its source in a confluence of research approaches that follow a decompositional approach to meaning and, thus, defines simple lexemes and affixes by way of a systematic representation that is achieved via a constrained formal language that enforces consistency of annotation. Lexical-semantic representations in LSF consist of two parts: the Semantic/Grammatical Skeleton and the Semantic/Pragmatic Body (henceforth ‘skeleton’ and ‘body’ respectively). The skeleton is comprised of features that are of relevance to the syntax. These features act as functions and may take arguments. Functions and arguments of a skeleton are hierarchically arranged. The body encodes all those aspects of meaning that are perceptual, cultural, and encyclopedic.
Features in LSF are used in (a) a cross-categorial, (b) an equipollent, and (c) a privative way. This means that they are used to account for the distinction between the major ontological categories, may have a binary (i.e., positive or negative) value, and may or may not form part of the skeleton of a given lexeme. In order to account for the fact that several distinct parts integrate into a single referential unit that projects its arguments to the syntax, LSF makes use of the Principle of Co-indexation. Co-indexation is a device needed in order to tie together the arguments that come with different parts of a complex word to yield only those arguments that are syntactically active.
LSF has an important impact on the study of the morphology-lexical semantics interface and provides a unitary theory of meaning in word formation.
Lexical semantics is the study of word meaning. Descriptively speaking, the main topics studied within lexical semantics involve either the internal semantic structure of words, or the semantic relations that occur within the vocabulary. Within the first set, major phenomena include polysemy (in contrast with vagueness), metonymy, metaphor, and prototypicality. Within the second set, dominant topics include lexical fields, lexical relations, conceptual metaphor and metonymy, and frames. Theoretically speaking, the main theoretical approaches that have succeeded each other in the history of lexical semantics are prestructuralist historical semantics, structuralist semantics, and cognitive semantics. These theoretical frameworks differ as to whether they take a system-oriented rather than a usage-oriented approach to word-meaning research but, at the same time, in the historical development of the discipline, they have each contributed significantly to the descriptive and conceptual apparatus of lexical semantics.

The linguistic landscape (henceforth LL) has proven to be a fruitful approach for investigating various societal dimensions of written language use in the public sphere. First introduced in the context of bilingual Canada as a gauge for measuring ethnolinguistic vitality, in the 21st century it is the focus of a thriving field of inquiry with its own conference series, an increasing number of publications, and an international journal dedicated exclusively to investigating language and other semiotic resources used in the public arena. The scholarship in this domain has centered on European and North American geographical sites; however, an increasingly voluminous share of studies addresses the LL of sites across the world through both books and articles. African contributions have added an important dimension to this knowledge base as southern multilingualisms bring into question the very concept of language in that speakers and writers draw on their rich linguistic repertoires, avoiding any compartmentalization or separation of what is traditionally conceived of as languages. The LL of Ethiopia has contributed to this growing base of empirical studies in the exploration of language policy issues, identity constructions, language contact, and the sociolinguistics of globalization. A new language policy of ethnic federalism was introduced to the country in the 1990s following a civil war and through a new constitution. This policy was set to recognize the various ethnolinguistic groups in the country and the official use of ethnic/regional languages to satisfy local political and educational needs. Through this, languages previously unwritten required a script in order for speakers to communicate in them in written texts. And many regions have chosen the Latin script above the Ethiopic script. Nonetheless, some languages remain invisible in the public sphere. These events create an exciting laboratory for studying the LL. Given the change of language policy since the late 20th century and the fast-growing economy of Ethiopia (one of the poorest countries on the continent) the manifest and increasingly visible display of languages in the LL provides an excellent lens for studying various sociolinguistic phenomena.

The linguistic study of literature addresses the ways in which language is differently organized in verbal art (literature). Form is added to language, altered, attenuated, and differently grouped. These different kinds of organization are normatively subject to limits, some derived from limits on general or language-specific linguistic form. However, linguistic form can, in principle, be altered in any way at all, in avant-garde texts, for instance, or to produce artificial languages for literature; this possibility raises the general question of whether some organizations of literary language are cognitively transparent and others are cognitively opaque.
Of the various added forms, the most extensively studied has been metrical form, which requires the words of the text to be grouped into lines. Metrical form combines a non-linguistic counting system with a rhythmic system, which adapts the rhythmic systems of ordinary phonology. The metrical line may have a special status, as a cognitively privileged level of grouping, possibly because it is fitted to working memory. Rhyme and alliteration are two common kinds of added form; most linguistic interest has been in what counts as “similarity of sound” between two words, whether at a surface or underlying level. Rhyming and alliterating words are distributed relative to the grouping into lines and other constituents. The other major kind of added form is parallelism, where two sections of text are structurally similar, usually in syntax and vocabulary.
All literary texts have a discourse structure, which includes division into various types of group or constituent, including the division of a narrative into episodes, exploiting verbal cues of episodic boundaries. Narratives also require the tracking of referents such as people and objects across the discourse, which draws on the study of pronominals. Literary texts may also have a distinctive vocabulary, borrowing or inventing words to an unusual degree, and engaging in various kinds of word play.
Literary texts have “style” and “markedness,” ways in which the language varies in noticeable ways but without coding a different linguistic semantics. These stylistic variations are sometimes treated as having determinate interpretations, but there are also approaches to stylistic variations in literature, which treat them as having a non-determinate relation to meaning. Literature cannot have a different semantics or pragmatics from ordinary language, but meaning can be “difficult” in literature in ways not characteristic of much ordinary language (but in common with ritual speech and other ways of speaking).
A major mode of linguistic investigation involves corpora, over which statistical analyses are undertaken. This has a relation to the question of whether our literary-linguistic knowledge has a probabilistic basis, a question that ties the study of language to questions of expectation in aesthetics (e.g., music) more generally. Literature exists in various modalities—writing, oral literature, and signed literature—and linguistic approaches to literature have been sensitive to this, as well as to the special questions about how texts are set to music in songs.

Mayan languages are spoken by over 5 million people in Guatemala, Mexico, Belize, and Honduras. There are around 30 different languages today, ranging in size from fairly large (about a million speakers) to very small (fewer than 30 speakers). All Mayan languages are endangered given that at least some children in some communities are not learning the language, and two languages have disappeared since European contact. Mayas developed the most elaborated and most widely attested writing system in the Americas (starting about 300 BC).
The sounds of Mayan languages consist of a voiceless stop and affricate series with corresponding glottalized stops (either implosive and ejective) and affricates, glottal stop, voiceless fricatives (including h in some of them inherited from Proto-Maya), two to three nasals, three to four approximants, and a five vowel system with contrasting vowel length (or tense/lax distinctions) in most languages. Several languages have developed contrastive tone.
The major word classes in Mayan languages include nouns, verbs, adjectives, positionals, and affect words. The difference between transitive verbs and intransitive verbs is rigidly maintained in most languages. They usually use the same aspect markers (but not always). Intransitive verbs only indicate their subjects while transitive verbs indicate both subjects and objects. Some languages have a set of status suffixes which is different for the two classes. Positionals are a root class whose most characteristic word form is a non-verbal predicate. Affect words indicate impressions of sounds, movements, and activities. Nouns have a number of different subclasses defined on the basis of characteristics when possessed, or the structure of compounds. Adjectives are formed from a small class of roots (under 50) and many derived forms from verbs and positionals.
Predicate types are transitive, intransitive, and non-verbal. Non-verbal predicates are based on nouns, adjectives, positionals, numbers, demonstratives, and existential and locative particles. They are distinct from verbs in that they do not take the usual verbal aspect markers. Mayan languages are head marking and verb initial; most have VOA flexible order but some have VAO rigid order. They are morphologically ergative and also have at least some rules that show syntactic ergativity. The most common of these is a constraint on the extraction of subjects of transitive verbs (ergative) for focus and/or interrogation, negation, or relativization. In addition, some languages make a distinction between agentive and non-agentive intransitive verbs. Some also can be shown to use obviation and inverse as important organizing principles. Voice categories include passive, antipassive and agent focus, and an applicative with several different functions.

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).

Metrical structure refers to the phonological representations capturing the prominence relationships between syllables, usually manifested phonetically as differences in levels of stress. There is considerable diversity in the range of stress systems found cross-linguistically, although attested patterns represent a small subset of those that are logically possible. Stress systems may be broadly divided into two groups, based on whether they are sensitive to the internal structure, or weight, of syllables or not, with further subdivisions based on the number of stresses per word and the location of those stresses. An ongoing debate in metrical stress theory concerns the role of constituency in characterizing stress patterns. Certain approaches capture stress directly in terms of a metrical grid in which more prominent syllables are associated with a greater number of grid marks than less prominent syllables. Others assume the foot as a constituent, where theories differ in the inventory of feet they assume. Support for foot-based theories of stress comes from segmental alternations that are explicable with reference to the foot but do not readily emerge in an apodal framework. Computational tools, increasingly, are being incorporated in the evaluation of phonological theories, including metrical stress theories. Computer-generated factorial typologies provide a rigorous means for determining the fit between the empirical coverage afforded by metrical theories and the typology of attested stress systems. Computational simulations also enable assessment of the learnability of metrical representations within different theories.

Middle English is the name given to the English of the period from approximately 1100 to approximately 1450. This period is marked by substantial developments in all areas of English grammar. It is also the period of English when different dialects are the most fully attested in the texts. At the beginning of the Middle English period, the sociolinguistic status of English was low due to the Norman Invasion, and although religious texts of Old English composition continued to be copied and updated, few original compositions are extant. By the end of the period, English had regained its status as the language of government, law, and literature generally.
Although some notable changes to the phonemic inventory of consonants date from the Middle English period, the most dramatic phonological developments of the period involve vowels. The reduction of the vowels of unstressed syllables, one of the changes that marks the beginning of the Middle English period, is a phonological change with substantial morphological effects, as it substantially reduced the number of distinctive inflectional forms. Constituent order replaced case marking as the primary means of signaling grammatical relations. By the end of the Middle English period, subject-verb-object order had become established as the norm.
The lexicon of English was transformed in this period by an enormous influx of French words. The role of derivational morphology declined as its functions were to some extent replaced by the adoption of French words. Most Scandinavian loans in English first appear in the texts of this period. The Scandinavian loans are typically everyday words, while the words adopted from French are more often in areas of government, law, and higher culture, reflecting the nature of the contact between English speakers and the speakers of these languages.
The density of the Scandinavian population in the northern part of England is generally held to be responsible for the earlier appearance of changes in the north than in the south. The replacement of the third person plural personal pronoun hie by the Scandinavian they is an example of a development which is apparent only in the north early in Middle English but became general in English by the end of this period.
An important phonological development of later Middle English is the beginning of the Great Vowel Shift, which affected long vowels and involved successive changes and was implemented differently in different dialects, the north-south divide being the most evident.
Early Middle English is a language that cannot be understood by Modern English readers without special study, while the language of the late Middle English period, especially that coming from the London area, can be understood with the heavy use of explanatory notes.
