The research of the group includes language documentation, description of grammar, lexical description, and reconstruction of the evolution and change of lexical and grammatical typology.
Researchers are involved in language documentation, both on living languages, as well as historical, literary languages. The fieldwork and documentation cover several continents, including (in alphabetical order) Basque (Holmer 2006), Jamtlandic and Elfdalian (Van Epps and Carling 2017, 2019, Van Epps, Carling and Sapir 2019) Kamaiurá (Carling, Cronhamn, Skute and Kamaiurá 2017), Kammu (Svantesson & Holmer 2014), Puyuma (Karlsson & Holmer 2011, 2012), Romani Kelderash (Carling, Demetri, Dimiter-Taikon, Lindell and Schwartz 2016), Scandoromani (Lindell, Djerf and Carling 2008, Carling, Lindell and Ambrazaitis 2014), Seediq (Holmer 2012, Holmer & Billings 2014), and Tocharian (Carling 2009, 2012, 2017, to appear, to appear). Ongoing PhD projects document Circassian (Filip Larsson), Baniwa (Sandra Cronhamn), and Bunun, Puyuma and Greenlandic (Victor Bogren Svensson). A large part of the fieldwork data is stored on the Corpus Server of the Lund Humanities Lab. Fieldwork data is used as a basis for populating the large-scale database infrastructure DiACL. As part of the language evolution research, the research group compiles vocabularies and grammar features, by fieldwork and documentation, from a large number of languages around the world (the infrastructure currently hosts data from around 600 languages). The data is available open access via the database DiACL (Carling et al 2017) and Concepticon (List et al 2019) (lexical data).
Description of grammar
Grammatical description from a typological perspective is a vital part of the language documentation program. Grammar descriptions include a study on patterns of language mixture in Scandoromani (Carling, Lindell and Ambrazaitis 2014), a grammatical description of Kammu (Holmer et al forthcoming), descriptions of grammatical patterns of Romani Kelderash and other varieties of Romani chib (Carling 2012, Carling et al 2016). Ongoing PhD projects look at affixation in grammar from a phylogenetic and areal perspective, with focus on the Caucasus region (Filip Larsson), gender and classifier systems in Baniwa (Sandra Cronhamn), and grammatical patterns in Formosan and Innuit languages (Victor Bogren Svensson).
Lexical description projects include production of lexical resources (as part of language documentation), including dictionaries of Scandoromani (Carling 2005, Lindell, Djerf and Carling 2008, Carling, Lindell and Ambrazaitis 2014) and Tocharian (Carling, Pinault and Winter 2009, Carling and Pinault to appear). An ongoing research topic is gender and classifier assignment, studied on vocabularies of languages. We investigate gender assignment in Scandinavian and specifically the Jamtlandic dialect of Sweden (Van Epps and Carling 2017, Van Epps and Carling 2019, Van Epps, Carling and Sapir to appear). An ongoing PhD project studies gender and classifiers in the Arawak language Baniwa (Sandra Cronhamn).
Typology and evolution of grammar
Besides studying the grammar of individual languages from a typological perspective, we investigate grammar from a large-scale, typological and evolutionary perspective. We have formulated principles for using ancient data for phylogenetics (Carling ed. 2019, Carling, Larsson, Cathcart, Johansson, Holmer and Round 2018, Carling, Cathcart and Round in press), as well as contrasting grammar against other data types by GIS (Carling, Eriksen, Holmer, Van de Weijer 2013).
A study investigates areal pressure in grammatical evolution with respect to language complexity (Cathcart, Carling, Larsson, Johansson and Round 2018). In a large study (Carling and Cathcart to appear, Carling and Cathcart to appear) we build an evolutionary model for grammar reconstruction, based on Indo-European, where we confirm that universal hierarchies, based on economy and frequency, impact grammar evolution.
Another research theme is lexical evolution, which we investigate data from a macro-perspective, using computational methods. We observe that vocabularies have differentiating change patterns depending on their cultural classification (Carling ed. 2019, Carling, Cronhamn, Eriksen, Farren, Johansson, Van de Weijer 2019). We also conclude that patterns of borrowability in the lexicon are caused by culture and prestige equally (Carling, Cronhamn, Farren, Aliyev and Frid 2019). Ongoing research looks at gender assignment in Indo-European and other gendered families, such as the Northwest Caucasian and Nakh-Dagestanian families.
A research group looks at sound symbolism, both from a general theoretical perspective (Johansson 2014, Carling and Johansson 2014), from the perspective of lexical change (Johansson and Carling 2015, Carling 2017), and with respect to colour terms (Johansson and Anikin 2019). A large-scale study of sound symbolism in several hundred languages reveals that a substantial part of basic vocabulary has a form-function association (Johansson, Anikin, Carling, Holmer 2020).
