In this paper, we present a comparative study of mouth actions in three European sign languages: British Sign Language (BSL), Nederlandse Gebarentaal (Sign Language of the Netherlands, NGT), and Swedish Sign Language (SSL). We propose a typology for, and report the frequency distribution of, the different types of mouth actions observed. In accordance with previous studies, we find the three languages remarkably similar — both in the types of mouth actions they use, and in how these mouth actions are distributed. We then describe how mouth actions can extend over more than one manual sign. This spreading of mouth actions is the primary focus of this paper. Based on an analysis of comparable narrative material in the three languages, we demonstrate that the direction as well as the source and goal of spreading may be language-specific.

Signed languages are similar to spoken languages in the overall organisation of their grammars, displaying a prosodic level of organisation that is not isomorphic to the syntactic organisation. Their rich inventory of manual and non-manual features allows for a prolific range of functions if used prosodically. New data from Sign Language of the Netherlands (NGT, Nederlandse Gebarentaal) are discussed to demonstrate that focused constituents are not marked by a single prosodic feature, but rather by multiple properties that can also have other functions in the prosodic phonology of the language. These findings are integrated in an overall model of sign language prosody that emphasises the distinction between phonetic appearance and phonological representation and that allows for the interaction of linguistic and paralinguistic cues in visual communication.

In this article we investigate topics in NGT (Sign Language of the Netherlands
