This article analyses Locating Adverbials (LAs) such as 'un peu plus tard', 'ce matin', 'deux kilomètres plus loin' (a little later, this morning, two kilometers further) when they are dislocated to the left of the sentence (IP Adjuncts cases). Although not discourse connectives, in such a position, they seem to play an important part in structuring discourse. It is this contribution of LAs to discourse that we tackle, providing a descriptive analysis and a formal account grounded on Segmented Discourse Representation Theory. In particular, we deal with the frame introducer role of the LAs and with spatio-temporal interpretations of these markers occurring in trajectory descriptions.
