Sign Language & Linguistics - Volume 14, Issue 2, 2011

This study investigates the frequency and functions of a ubiquitous form in conversational NZSL discourse glossed as palm-up. Dictionaries show that it is a polysemous vocabulary item in NZSL, although many of its uses in discourse are not accounted for in the lexicon. Analysis of discourse data from 20 signers shows it to be the second most frequently occuring item, and to exhibit phonological variation. We identify and discuss four (non-exclusive) functions of palm-up in this data: cohesive, modal, interactive, and manual frame for unpredictable mouthings (codemixing). Correspondences in form, linguistic context, and meaning are found between uses of palm-up in NZSL, similar forms in other signed languages, and co-speech palm gestures. The study affirms previous descriptions of this form as having properties of both gesture and sign, and suggests that it also has features of a discourse marker.

Mouthings and mouth gestures are omnipresent in Sign Language of the Netherlands (NGT). Mouthings in NGT commonly have their origin in spoken Dutch. We conducted a corpus study to explore how frequent mouthings in fact are in NGT, whether there is variation within and between signs in mouthings, and how frequent temporal reduction occurs in mouthings. Answers to these questions can help us classify mouthings as being specified in the sign lexicon or as being instances of code-blending. We investigated a sample of 20 frequently occurring signs. We found that each sign in the sample co-occurs frequently with a mouthing, usually that of a specific Dutch lexical item. On the other hand, signs show variation in the way they co-occur with mouthings and mouth gestures.By using a relatively large amount of natural data, we succeeded in gaining more insight into the way mouth actions are utilized in sign languages.
