The joint French-German research project ‘Uncovering Verb-Second Effects. An Interface-Based Typology’ (acronym: UV2), financed for the period 2019-2022 by the Agence Nationale de la Recherche (French Research Foundation) and the Deutsche Forschungsgemeinschaft (German Research Foundation), investigates adjacency requirements obtaining in syntactic configurations in which the finite verb occurs in second position in a range of typologically and genetically related as well as unrelated non-(exact) verb second (V2) languages with basic SVO or SOV word order (Basque, Kyrgyz, Kazakh, Uzbek, Sorbian as well as Old and Modern Romance). 

Fundamentally, the project aims at expanding the perimeter of languages relevant to the verb second typology by exploring the extent as well as the particulars of V2 effects in the languages under scrutiny, by assessing the possible impact of language contact, and by elucidating the existence of different factors from various domains of grammar which lie behind the phenomenon of V2.
