“…We assume that they are not. Before children start using multiword utterances, they can produce strings that contain more than one meaningful word, by adding "dummy forms" (e.g., Barrett, 1989;Cutler & Swinney, 1987;Dore, Franklin, Miller & Ramer, 1976;Bloom, 1973;Galligan, 1987), filler elements (Bassano & Eme, 2001;Kilani-Schoch & Dressler, 2001;López Ornat, 2001;Peters & Menn, 1993;Taelman et al, 2009;Veneziano, Sinclair & Berthoud, 1990;Veneziano & Sinclair, 2000) or produce two meaningful words articulated as a two word utterance referring however each to a different communicative intention (e.g., Veneziano et al, 1990). We suppose that conceptual and linguistic developments are needed in order to use articulatory abilites to produce multiword utterances.…”
