Words are sensitive to syntactic context. Argument realization is the study of the relation between argument-taking words, the syntactic contexts they appear in and the interpretive properties that constrain the relation between them.
Blocking can be defined as the non-occurrence of some linguistic form, whose existence could be expected on general grounds, due to the existence of a rival form. *Oxes, for example, is blocked by oxen, *stealer by thief. Although blocking is closely associated with morphology, in reality the competing “forms” can not only be morphemes or words, but can also be syntactic units. In German, for example, the compound Rotwein ‘red wine’ blocks the phrasal unit *roter Wein (in the relevant sense), just as the phrasal unit rote Rübe ‘beetroot; lit. red beet’ blocks the compound *Rotrübe. In these examples, one crucial factor determining blocking is synonymy; speakers apparently have a deep-rooted presumption against synonyms. Whether homonymy can also lead to a similar avoidance strategy, is still controversial. But even if homonymy blocking exists, it certainly is much less systematic than synonymy blocking.
In all the examples mentioned above, it is a word stored in the mental lexicon that blocks a rival formation. However, besides such cases of lexical blocking, one can observe blocking among productive patterns. Dutch has three suffixes for deriving agent nouns from verbal bases, -er, -der, and -aar. Of these three suffixes, the first one is the default choice, while -der and -aar are chosen in very specific phonological environments: as Geert Booij describes in The Morphology of Dutch (2002), “the suffix -aar occurs after stems ending in a coronal sonorant consonant preceded by schwa, and -der occurs after stems ending in /r/” (p. 122). Contrary to lexical blocking, the effect of this kind of pattern blocking does not depend on words stored in the mental lexicon and their token frequency but on abstract features (in the case at hand, phonological features).
Blocking was first recognized by the Indian grammarian Pāṇini in the 5th or 4th century

Computational phonology studies the nature of the computations necessary and sufficient for characterizing phonological knowledge. As a field it is informed by the theories of computation and phonology.
The computational nature of phonological knowledge is important because at a fundamental level it is about the psychological nature of memory as it pertains to phonological knowledge. Different types of phonological knowledge can be characterized as computational problems, and the solutions to these problems reveal their computational nature. In contrast to syntactic knowledge, there is clear evidence that phonological knowledge is computationally bounded to the so-called regular classes of sets and relations. These classes have multiple mathematical characterizations in terms of logic, automata, and algebra with significant implications for the nature of memory. In fact, there is evidence that phonological knowledge is bounded by particular subregular classes, with more restrictive logical, automata-theoretic, and algebraic characterizations, and thus by weaker models of memory.
Displacement is a ubiquitous phenomenon in natural languages. Grammarians often speak of displacement in cases where the rules for the canonical word order of a language lead to the expectation of finding a word or phrase in a particular position in the sentence whereas it surfaces instead in a different position and the canonical position remains empty: ‘Which book did you buy?’ is an example of displacement because the noun phrase ‘which book’, which acts as the grammatical object in the question, does not occur in the canonical object position, which in English is after the verb. Instead, it surfaces at the beginning of the sentence and the object position remains empty. Displacement is often used as a diagnostic for constituent structure because it affects only (but not all) constituents. In the clear cases, displaced constituents show properties associated with two distinct linear and hierarchical positions. Typically, one of these two positions c-commands the other and the displaced element is pronounced in the c-commanding position. Displacement also shows strong interactions with the path between the empty canonical position and the position where the element is pronounced: one often encounters morphological changes along this path and evidence for structural placement of the displaced constituent, as well as constraints on displacement induced by the path.
The exact scope of displacement as an analytically unified phenomenon varies from theory to theory. If more then one type of syntactic displacement is recognized, the question of the interaction between movement types arises. Displacement phenomena are extensively studied by syntacticians. Their enduring interest derives from the fact that the complex interactions between displacement and other aspects of syntax offer a powerful probe into the inner workings and architecture of the human syntactic faculty.

Distributed Morphology (DM) is a framework in theoretical morphology, characterized by two core tenets: (i) that the internal hierarchical structure of words is, in the first instance, syntactic (complex words are derived syntactically), and (ii) that the syntax operates on abstract morphemes, defined in terms of morphosyntactic features, and that the spell-out (realization, exponence) of these abstract morphemes occurs after the syntax. Distributing the functions of the classical morpheme in this way allows for analysis of mismatches between the minimal units of grammatical combination and the minimal units of sound. Much work within the framework is nevertheless guided by seeking to understand restrictions on such mismatches, balancing the need for the detailed description of complex morphological data in individual languages against an attempt to explain broad patterns in terms of restrictions imposed by grammatical principles.

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).
