It has been an ongoing issue within generative linguistics how to properly analyze morpho-phonological processes. Morpho-phonological processes typically have exceptions, but nonetheless they are often productive. Such productive, but exceptionful, processes are difficult to analyze, since grammatical rules or constraints are normally invoked in the analysis of a productive pattern, whereas exceptions undermine the validity of the rules and constraints. In addition, productivity of a morpho-phonological process may be gradient, possibly reflecting the relative frequency of the relevant pattern in the lexicon. Simple lexical listing of exceptions as suppletive forms would not be sufficient to capture such gradient productivity of a process with exceptions. It is then necessary to posit grammatical rules or constraints even for exceptionful processes as long as they are at least in part productive. Moreover, the productivity can be correctly estimated only when the domain of rule application is correctly identified. Consequently, a morpho-phonological process cannot be properly analyzed unless we possess both the correct description of its application conditions and the appropriate stochastic grammatical mechanisms to capture its productivity.
The same issues arise in the analysis of morpho-phonological processes in Korean, in particular, n-insertion, sai-siot, and vowel harmony. Those morpho-phonological processes have many exceptions and variations, which make them look quite irregular and unpredictable. However, they have at least a certain degree of productivity. Moreover, the variable application of each process is still systematic in that various factors, phonological, morphosyntactic, sociolinguistic, and processing, contribute to the overall probability of rule application. Crucially, grammatical rules and constraints, which have been proposed within generative linguistics to analyze categorical and exceptionless phenomena, may form an essential part of the analysis of the morpho-phonological processes in Korean.
For an optimal analysis of each of the morpho-phonological processes in Korean, the correct conditions and domains for its application need to be identified first, and its exact productivity can then be measured. Finally, the appropriate stochastic grammatical mechanisms need to be found or developed in order to capture the measured productivity.

Autosegments were introduced by John Goldsmith in his 1976 M.I.T. dissertation to represent tone and other suprasegmental phenomena. Goldsmith’s intuition, embodied in the term he created, was that autosegments constituted an independent, conceptually equal tier of phonological representation, with both tiers realized simultaneously like the separate voices in a musical score.
The analysis of suprasegmentals came late to generative phonology, even though it had been tackled in American structuralism with the long components of Harris’s 1944 article, “Simultaneous components in phonology” and despite being a particular focus of Firthian prosodic analysis. The standard version of generative phonology of the era (Chomsky and Halle’s The Sound Pattern of English) made no special provision for phenomena that had been labeled suprasegmental or prosodic by earlier traditions.
An early sign that tones required a separate tier of representation was the phenomenon of tonal stability. In many tone languages, when vowels are lost historically or synchronically, their tones remain. The behavior of contour tones in many languages also falls into place when the contours are broken down into sequences of level tones on an independent level or representation. The autosegmental framework captured this naturally, since a sequence of elements on one tier can be connected to a single element on another. But the single most compelling aspect of the early autosegmental model was a natural account of tone spreading, a very common process that was only awkwardly captured by rules of whatever sort. Goldsmith’s autosegmental solution was the Well-Formedness Condition, requiring, among other things, that every tone on the tonal tier be associated with some segment on the segmental tier, and vice versa. Tones thus spread more or less automatically to segments lacking them. The Well-Formedness Condition, at the very core of the autosegmental framework, was a rare constraint, posited nearly two decades before Optimality Theory.
One-to-many associations and spreading onto adjacent elements are characteristic of tone but not confined to it. Similar behaviors are widespread in long-distance phenomena, including intonation, vowel harmony, and nasal prosodies, as well as more locally with partial or full assimilation across adjacent segments.
The early autosegmental notion of tiers of representation that were distinct but conceptually equal soon gave way to a model with one basic tier connected to tiers for particular kinds of articulation, including tone and intonation, nasality, vowel features, and others. This has led to hierarchical representations of phonological features in current models of feature geometry, replacing the unordered distinctive feature matrices of early generative phonology. Autosegmental representations and processes also provide a means of representing non-concatenative morphology, notably the complex interweaving of roots and patterns in Semitic languages.
Later work modified many of the key properties of the autosegmental model. Optimality Theory has led to a radical rethinking of autosegmental mapping, delinking, and spreading as they were formulated under the earlier derivational paradigm.

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.

A relative clause is a clausal modifier that relates to a constituent of the sentence, typically a noun phrase. This is the antecedent or “head” of the relative construction. What makes the configuration special is that the subordinate clause contains a variable that is bound by the head. For instance, in the English sentence Peter recited a poem that Anne liked, the object of the embedded verb liked is relativized. In this example, the relative clause is a restrictive property, and the possible reference of a poem is narrowed to poems that Anne likes. However, it is also possible to construct a relative clause non-restrictively. If the example is changed to Peter recited this poem by Keats, which Anne likes, the relative clause provides additional information about the antecedent, and the internal variable, here spelled out by the relative pronoun which, is necessarily coreferential with the antecedent.
Almost all languages make use of (restrictive) relative constructions in one way or another. Various strategies of building relative clauses have been distinguished, which correlate at least partially with particular properties of languages, including word order patterns and the availability of certain pronouns. Relative clauses can follow or precede the head, or even include the head. Some languages make use of relative pronouns, while others use resumptive pronouns, or simply leave the relativized argument unpronounced in the subordinate clause. Furthermore, there is cross-linguistic variation in the range of syntactic functions that can be relativized. Notably, more than one type of relative clause can be present in one language. Special types of relative constructions include free relatives (with an implied pronominal antecedent), cleft constructions, and correlatives.
There is an extensive literature on the structural analysis of relative constructions. Questions that are debated include: How can different subtypes be distinguished? How does the internal variable relate to the antecedent? How can reconstruction and anti-reconstruction effects be explained? At what structural level is the relative clause attached to the antecedent or the matrix clause?
Within the Ryukyuan branch of the Japonic family of languages, present-day Okinawan retains numerous regional variants which have evolved for over a thousand years in the Ryukyuan Archipelago. Okinawan is one of the six Ryukyuan languages that UNESCO identified as endangered. One of the theoretically fascinating features is that there is substantial evidence for establishing a high central phonemic vowel in Okinawan although there is currently no overt surface [ï]. Moreover, the word-initial glottal stop [ʔ] in Okinawan is more salient than that in Japanese when followed by vowels, enabling recognition that all Okinawan words are consonant-initial. Except for a few particles, all Okinawan words are composed of two or more morae. Suffixation or vowel lengthening (on nouns, verbs, and adjectives) provides the means for signifying persons as well as things related to human consumption or production. Every finite verb in Okinawan terminates with a mood element. Okinawan exhibits a complex interplay of mood or negative elements and focusing particles. Evidentiality is also realized as an obligatory verbal suffix.
Nominalization refers both to the process by which complex nouns are created and to the complex nouns that are derived by that process. Nominalizations common in the languages of the world include event/result nouns, personal or participant nouns (agent, patient, location, etc.), as well as collectives and abstracts. It is common for nominalizations to be highly polysemous. Theoretical issues concerning nominalization typically stem from the question of how to account for this pervasive polysemy. Within generative grammar, both syntactic and lexicalist approaches have been proposed. The issue of polysemy in nominalization has also been of interest within cognitive and functional frameworks. The article considers, finally, the extent to which nominalization is subject to competition and blocking.
A fundamental difference in theoretical models of morphology and, particularly, of the syntax–morphology interface is that between endoskeletal and exoskeletal approaches. In the former, more traditional, endoskeletal approaches, open-class lexical items like cat or sing are held to be inherently endowed with a series of formal features that determine the properties of the linguistic expressions in which they appear. In the latter, more recent, exoskeletal approaches, it is rather the morphosyntactic configurations, independently produced by the combination of abstract functional elements, that determine those properties. Lexical items, in this latter approach, are part of the structure but, crucially, do not determine it.
Conceptually, although a correlation is usually made between endoskeletalism and lexicalism/projectionism, on the one hand, and between exoskeletalism and (neo)constructionism, on the other, things are actually more complicated, and some frameworks exist that seem to challenge those correlations, in particular when the difference between word and morpheme is taken into account.
Empirically, the difference between these two approaches to morphology and the morphology-syntax interface comes to light when one examines how each one treats a diversity of word-related phenomena: morphosyntactic category and category shift in derivational processes, inflectional class, nominal properties like mass or count, and verbal properties like agentivity and (a)telicity.
Compound and complex predicates—predicates that consist of two or more lexical items and function as the predicate of a single sentence—present an important class of linguistic objects that pertain to an enormously wide range of issues in the interactions of morphology, phonology, syntax, and semantics. Japanese makes extensive use of compounding to expand a single verb into a complex one. These compounding processes range over multiple modules of the grammatical system, thus straddling the borders between morphology, syntax, phonology, and semantics. In terms of degree of phonological integration, two types of compound predicates can be distinguished. In the first type, called tight compound predicates, two elements from the native lexical stratum are tightly fused and inflect as a whole for tense. In this group, Verb-Verb compound verbs such as arai-nagasu [wash-let.flow] ‘to wash away’ and hare-agaru [sky.be.clear-go.up] ‘for the sky to clear up entirely’ are preponderant in numbers and productivity over Noun-Verb compound verbs such as tema-doru [time-take] ‘to take a lot of time (to finish).’
The second type, called loose compound predicates, takes the form of “Noun + Predicate (Verbal Noun [VN] or Adjectival Noun [AN]),” as in post-syntactic compounds like [sinsya : koonyuu] no okyakusama ([new.car : purchase] GEN customers) ‘customer(s) who purchase(d) a new car,’ where the symbol “:” stands for a short phonological break. Remarkably, loose compounding allows combinations of a transitive VN with its agent subject (external argument), as in [Supirubaagu : seisaku] no eiga ([Spielberg : produce] GEN film) ‘a film/films that Spielberg produces/produced’—a pattern that is illegitimate in tight compounds and has in fact been considered universally impossible in the world’s languages in verbal compounding and noun incorporation.
In addition to a huge variety of tight and loose compound predicates, Japanese has an additional class of syntactic constructions that as a whole function as complex predicates. Typical examples are the light verb construction, where a clause headed by a VN is followed by the light verb suru ‘do,’ as in Tomodati wa sinsya o koonyuu (sae) sita [friend TOP new.car ACC purchase (even) did] ‘My friend (even) bought a new car’ and the human physical attribute construction, as in Sensei wa aoi me o site-iru [teacher TOP blue eye ACC do-ing] ‘My teacher has blue eyes.’ In these constructions, the nominal phrases immediately preceding the verb suru are semantically characterized as indefinite and non-referential and reject syntactic operations such as movement and deletion. The semantic indefiniteness and syntactic immobility of the NPs involved are also observed with a construction composed of a human subject and the verb aru ‘be,’ as Gakkai ni wa oozei no sankasya ga atta ‘There was a large number of participants at the conference.’ The constellation of such “word-like” properties shared by these compound and complex predicates poses challenging problems for current theories of morphology-syntax-semantics interactions with regard to such topics as lexical integrity, morphological compounding, syntactic incorporation, semantic incorporation, pseudo-incorporation, and indefinite/non-referential NPs.

The syntax–phonology interface refers to the way syntax and phonology are interconnected. Although syntax and phonology constitute different language domains, it seems undisputed that they relate to each other in nontrivial ways. There are different theories about the syntax–phonology interface. They differ in how far each domain is seen as relevant to generalizations in the other domain, and in the types of information from each domain that are available to the other.
Some theories see the interface as unlimited in the direction and types of syntax–phonology connections, with syntax impacting on phonology and phonology impacting on syntax. Other theories constrain mutual interaction to a set of specific syntactic phenomena (i.e., discourse-related) that may be influenced by a limited set of phonological phenomena (namely, heaviness and rhythm). In most theories, there is an asymmetrical relationship: specific types of syntactic information are available to phonology, whereas syntax is phonology-free.
The role that syntax plays in phonology, as well as the types of syntactic information that are relevant to phonology, is also a matter of debate. At one extreme, Direct Reference Theories claim that phonological phenomena, such as external sandhi processes, refer directly to syntactic information. However, approaches arguing for a direct influence of syntax differ on the types of syntactic information needed to account for phonological phenomena, from syntactic heads and structural configurations (like c-command and government) to feature checking relationships and phase units. The precise syntactic information that is relevant to phonology may depend on (the particular version of) the theory of syntax assumed to account for syntax–phonology mapping. At the other extreme, Prosodic Hierarchy Theories propose that syntactic and phonological representations are fundamentally distinct and that the output of the syntax–phonology interface is prosodic structure. Under this view, phonological phenomena refer to the phonological domains defined in prosodic structure. The structure of phonological domains is built from the interaction of a limited set of syntactic information with phonological principles related to constituent size, weight, and eurhythmic effects, among others. The kind of syntactic information used in the computation of prosodic structure distinguishes between different Prosodic Hierarchy Theories: the relation-based approach makes reference to notions like head-complement, modifier-head relations, and syntactic branching, while the end-based approach focuses on edges of syntactic heads and maximal projections. Common to both approaches is the distinction between lexical and functional categories, with the latter being invisible to the syntax–phonology mapping. Besides accounting for external sandhi phenomena, prosodic structure interacts with other phonological representations, such as metrical structure and intonational structure.
As shown by the theoretical diversity, the study of the syntax–phonology interface raises many fundamental questions. A systematic comparison among proposals with reference to empirical evidence is lacking. In addition, findings from language acquisition and development and language processing constitute novel sources of evidence that need to be taken into account. The syntax–phonology interface thus remains a challenging research field in the years to come.
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-
