Natural language allows questioning into embedded clauses. One strategy for doing so involves structures like the following: [CP-1 whi [TP DP V [CP-2 … ti …]]], where a wh-phrase that thematically belongs to the embedded clause appears in the matrix scope position. A possible answer to such a question must specify values for the fronted wh-phrase. This is the extraction strategy seen in languages like English. An alternative strategy involves a structure in which there is a distinct wh-phrase in the matrix clause. It is manifested in two types of structures. One is a close analog of extraction, but for the extra wh-phrase: [CP-1 whi [TP DP V [CP-2 whj [TP…tj…]]]]. The other simply juxtaposes two questions, rather than syntactically subordinating the second one: [CP-3 [CP-1 whi [TP…]] [CP-2 whj [TP…]]]. In both versions of the second strategy, the wh-phrase in CP-1 is invariant, typically corresponding to the wh-phrase used to question propositional arguments. There is no restriction on the type or number of wh-phrases in CP-2. Possible answers must specify values for all the wh-phrases in CP-2. This strategy is variously known as scope marking, partial wh movement or expletive wh questions. Both strategies can occur in the same language. German, for example, instantiates all three possibilities: extraction, subordinated, as well as sequential scope marking. The scope marking strategy is also manifested in in-situ languages. Scope marking has been subjected to 30 years of research and much is known at this time about its syntactic and semantic properties. Its pragmatics properties, however, are relatively under-studied. The acquisition of scope marking, in relation to extraction, is another area of ongoing research. One of the reasons why scope marking has intrigued linguists is because it seems to defy central tenets about the nature of wh scope taking. For example, it presents an apparent mismatch between the number of wh expressions in the question and the number of expressions whose values are specified in the answer. It poses a challenge for our understanding of how syntactic structure feeds semantic interpretation and how alternative strategies with similar functions relate to each other.

Traditional approaches to semantic change typically focus on outcomes of meaning change and list types of change such as metaphoric and metonymic extension, broadening and narrowing, and the development of positive and negative meanings. Examples are usually considered out of context, and are lexical members of nominal and adjectival word classes.
However, language is a communicative activity that is highly dependent on context, whether that of the ongoing discourse or of social and ideological changes. Much recent work on semantic change has focused, not on results of change, but on pragmatic enabling factors for change in the flow of speech. Attention has been paid to the contributions of cognitive processes, such as analogical thinking, production of cues as to how a message is to be interpreted, and perception or interpretation of meaning, especially in grammaticalization. Mechanisms of change such as metaphorization, metonymization, and subjectification have been among topics of special interest and debate. The work has been enabled by the fine-grained approach to contextual data that electronic corpora allow.

Most linguists have heard of semantic compositionality. Some will have heard that it is the fundamental truth of semantics. Others will have been told that it is so thoroughly and completely wrong that it is astonishing that it is still being taught. The present article attempts to explain all this. Much of the discussion of semantic compositionality takes place in three arenas that are rather insulated from one another: (a) philosophy of mind and language, (b) formal semantics, and (c) cognitive linguistics and cognitive psychology. A truly comprehensive overview of the writings in all these areas is not possible here. However, this article does discuss some of the work that occurs in each of these areas. A bibliography of general works, and some Internet resources, will help guide the reader to some further, undiscussed works (including further material in all three categories).

Rich data gathered in experimental primatology in the last 40 years are beginning to benefit from analytical methods used in contemporary linguistics, especially in the area of semantics and pragmatics. These methods have started to clarify five questions: (i) What morphology and syntax, if any, do monkey calls have? (ii) What is the ‘lexical meaning’ of individual calls? (iii) How are the meanings of individual calls combined? (iv) How do calls or call sequences compete with each other when several are appropriate in a given situation? (v) How did the form and meaning of calls evolve? Four case studies from this emerging field of ‘primate linguistics’ provide initial answers, pertaining to Old World monkeys (putty-nosed monkeys, Campbell’s monkeys, and colobus monkeys) and New World monkeys (black-fronted Titi monkeys). The morphology mostly involves simple calls, but in at least one case (Campbell’s -oo) one finds a root–suffix structure, possibly with a compositional semantics. The syntax is in all clear cases simple and finite-state. With respect to meaning, nearly all cases of call concatenation can be analyzed as being semantically conjunctive. But a key question concerns the division of labor between semantics, pragmatics, and the environmental context (‘world’ knowledge and context change). An apparent case of dialectal variation in the semantics (Campbell’s krak) can arguably be analyzed away if one posits sufficiently powerful mechanisms of competition among calls, akin to scalar implicatures. An apparent case of noncompositionality (putty-nosed pyow–hack sequences) can be analyzed away if one further posits a pragmatic principle of ‘urgency’. Finally, rich Titi sequences in which two calls are re-arranged in complex ways so as to reflect information about both predator identity and location are argued not to involve a complex syntax/semantics interface, but rather a fine-grained interaction between simple call meanings and the environmental context. With respect to call evolution, the remarkable preservation of call form and function over millions of years should make it possible to lay the groundwork for an evolutionary monkey linguistics, illustrated with cercopithecine booms.
Hearers and readers make inferences on the basis of what they hear or read. These inferences are partly determined by the linguistic form that the writer or speaker chooses to give to her utterance. The inferences can be about the state of the world that the speaker or writer wants the hearer or reader to conclude are pertinent, or they can be about the attitude of the speaker or writer vis-à-vis this state of affairs. The attention here goes to the inferences of the first type. Research in semantics and pragmatics has isolated a number of linguistic phenomena that make specific contributions to the process of inference. Broadly, entailments of asserted material, presuppositions (e.g., factive constructions), and invited inferences (especially scalar implicatures) can be distinguished.
While we make these inferences all the time, they have been studied piecemeal only in theoretical linguistics. When attempts are made to build natural language understanding systems, the need for a more systematic and wholesale approach to the problem is felt. Some of the approaches developed in Natural Language Processing are based on linguistic insights, whereas others use methods that do not require (full) semantic analysis.
In this article, I give an overview of the main linguistic issues and of a variety of computational approaches, especially those stimulated by the RTE challenges first proposed in 2004.
In the linguistic literature, the term theme has several interpretations, one of which relates to discourse analysis and two others to sentence structure. In a more general (or global) sense, one may speak about the theme or topic (or topics) of a text (or discourse), that is, to analyze relations going beyond the sentence boundary and try to identify some characteristic subject(s) for the text (discourse) as a whole. This analysis is mostly a matter of the domain of information retrieval and only partially takes into account linguistically based considerations. The main linguistically based usage of the term theme concerns relations within the sentence. Theme is understood to be one of the (syntactico-) semantic relations and is used as the label of one of the arguments of the verb; the whole network of these relations is called thematic relations or roles (or, in the terminology of Chomskyan generative theory, theta roles and theta grids). Alternatively, from the point of view of the communicative function of the language reflected in the information structure of the sentence, the theme (or topic) of a sentence is distinguished from the rest of it (rheme, or focus, as the case may be) and attention is paid to the semantic consequences of the dichotomy (especially in relation to presuppositions and negation) and its realization (morphological, syntactic, prosodic) in the surface shape of the sentence. In some approaches to morphosyntactic analysis the term theme is also used referring to the part of the word to which inflections are added, especially composed of the root and an added vowel.
