This article studies a special type of verbal coordination in Swedish, pseudocoordination, which involves two verbs or verb phrases typically combined with och ‘and’. Although it consists of two verbs with a conjunction between them, pseudocoordination in many ways behaves like a subordinating complex-predicate construction. In the literature, pseudocoordination is treated more or less explicitly as a unitary phenomenon, but previous diachronic studies of some types of pseudocoordination point in slightly different directions regarding the origin of pseudocoordinations with different first verbs. It has been claimed that they originate in (canonical) verbal coordinations, but it has also been claimed that they are originally hypotactic structures in which the conjunction is a covert infinitival marker (both are typically pronounced in the same way today). To the best of our knowledge, the gå och V ‘walk/go and V’ construction has not previously been studied both diachronically and corpus-based. By examining gå och V in historical corpora, we therefore add to the historical knowledge of pseudocoordination with gå in Swedish. The gå och V construction is particularly interesting since it has multiple meanings and since it, unlike the bulk of Swedish pseudocoordinations, also has subordination counterparts in Modern Swedish.
