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.

The Social Network Analysis approach (SNA), also known as sociometrics or actor-network analysis, investigates social structure on the basis of empirically recorded social ties between actors. It thereby aims to explain e.g. the processes of flow of information, spreading of innovations, or even pathogens throughout the network by actor roles and their relative positions in the network based on quantitative and qualitative analyses. While the approach has a strong mathematical and statistical component, the identification of pertinent social ties also requires a strong ethnographic background. With regard to social categorization, SNA is well suited as a bootstrapping technique for highly dynamic communities and under-documented contexts. Currently, SNA is widely applied in various academic fields. For sociolinguists, it offers a framework for explaining the patterning of linguistic variation and mechanisms of language change in a given speech community.
The social tie perspective developed around 1940, in the field of sociology and social anthropology based on the ideas of Simmel, and was applied later in fields such as innovation theory. In sociolinguistics, it is strongly connected to the seminal work of Lesley and James Milroy and their Belfast studies (1978, 1985). These authors demonstrate that synchronic speaker variation is not only governed by broad societal categories but is also a function of communicative interaction between speakers. They argue that the high level of resistance against linguistic change in the studied community is a result of strong and multiplex ties between the actors. Their approach has been followed by various authors, including Gal, Lippi-Green, and Labov, and discussed for a variety of settings; most of them, however, are located in the Western world.
The methodological advantages could make SNA the preferred framework for variation studies in Africa due to the prevailing dynamic multilingual conditions, often on the backdrop of less standardized languages. However, rather few studies using SNA as a framework have yet been conducted. This is possibly due to the quite demanding methodological requirements, the overall effort, and the often highly complex linguistic backgrounds. A further potential obstacle is the pace of theoretical development in SNA. Since its introduction to sociolinguistics, various new measures and statistical techniques have been developed by the fast growing SNA community. Receiving this vast amount of recent literature and testing new concepts is likewise a challenge for the application of SNA in sociolinguistics.
Nevertheless, the overall methodological effort of SNA has been much reduced by the advancements in recording technology, data processing, and the introduction of SNA software (UCINET) and packages for network statistics in R (‘sna’). In the field of African sociolinguistics, a more recent version of SNA has been implemented in a study on contact-induced variation and change in Pana and Samo, two speech communities in the Northwest of Burkina Faso. Moreover, further enhanced applications are on the way for Senegal and Cameroon, and even more applications in the field of African languages are to be expected.
