Word formation in Latin is a fascinating subject that has been approached from different theoretical perspectives in recent decades. In this area there are some prominent topics that have captured the attention of various researchers.
Within the 20th International Colloquium on Latin Linguistics, held at the University of Las Palmas de Gran Canaria on 17-21 June 2019, we organized a workshop to congregate researchers who are working on word formation in Latin from different theoretical perspectives. Our goal was to begin a free and informal exchange of ideas in order to promote a fruitful cross-theoretical debate.
In this number of the journal we have collected a selection of the papers presented in the workshop. Each paper has been reviewed by two anonymous reviewers and we are very grateful to them for their efforts and help to improve the quality of the contributions. The papers offer different paths of argumentation and linguistic theorizing, which provide a substantial overview on the area of word formation in Latin today.

In this chapter, I concentrate on some of the most relevant theoretical and empirical issues where argument structure has been shown to play an important role. Below, I address the question of to what extent (verbal) argument structures are projected from lexical-semantic structures or are constructed outside of the lexicon. In doing so, I review the recent debate between projectionist and neo-constructionist approaches to argument structure. In this context, some special attention is also devoted to some syntactic approaches to argument structure like Hale and Keyser’s (1993, 2002) configurational theory, which has been very influential for many syntacticians interested in analyzing argument structure from a minimalist perspective.
