The International Conference on Historical Linguistics is the main conference for specialists in language change, and the 2013 conference in Oslo drew more than 300 participants, with 182 papers presented in the general session. The 16 papers selected for inclusion in this volume from the general session of ICHL 2013 not only provide a clear picture of the state of the art in various subfields of historical linguistics but also present recent insights in diachronic phonology, typology, morphology and morphosyntax. The languages and families covered include English, German, Scandinavian, French, Occitan, Portuguese, Sardinian, Spanish, Ancient Greek, Old Japanese and Austronesian. The volume will be useful to any linguist with an interest in diachronic matters as well as general linguistic theory.
