The Linguistics group at Uppsala University has a broad research profile. It studies phonetics, morphology, syntax, semantics and discourse in relation to a variety of languages. One important research theme is the typology of verbal semantic fields across different languages. Another important area is language documentation, which focuses on previously undescribed and endangered languages of South Asia, Africa and Australia, highlighting themes like language contact and language change, dialect and language variation, and typologically oriented studies. Another area is naturalistic and experimental studies of child and adult (second) language learners. Linguistics has participated in joint work with the units of Iranian and Turkic languages concerning typological work. Another interdisciplinary activity is cooperation with Speech and Language Pathology at the Faculty of Medicine.
