Abstract This thesis explores the mouthing occurrence rates across different registers (informative and narrative) and grammatical classes in Greek Sign Language (GSL). A general consensus has been reached dividing mouth activity into at least two subcategories of mouth actions: ‗mouth gestures‘ and ‗mouthings‘ (see edited volume by Boyes Braem & Sutton-Spence, 2001). Data consist of 45‘ of video recordings from six native and near-native1 signers, transcribed using a software tool for annotating multimedia video recordings (ELAN). In an effort to gain some control over the influence of individual variation, all six signers have an example of SL production in both registers. A combination of semantic, syntactic and morphological criteria (Schwager & Zeshan, 2008) has been utilized in order to classify all manual signs for their grammatical class, in an effort to study the potential impact of grammatical class on mouthing occurrence. Statistical analysis using a multivariate logistic regression model (Rbrul) showed both factors of register and grammatical class to be significant predictors of mouthing occurrence (p<0.001), results that comply with similar findings from most SLs studied to date (e.g. Sutton- Spence & Day, 2001; Nadolske & Rosenstock, 2007; Johnston et al., 2015). During the course of this study, I succeeded in identifying specific patterns of mouthing occurrence, thus gaining a better understanding of the way mouthings behave during sign language production. Keywords: [mouthings; variation; register; grammatical class; GSL]. 1 Signers with deaf parents are classified as ‗native‘, i.e. those who acquired GSL before the age of three, the pre-lingual learners (Bank et al., 2016), while the ‗near-native‘ term is used to describe a signer born in a hearing family, raised from the age of three in a boarding-school for deaf and Hard-of- Hearing children (HoH). Acknowledgments Sincere thanks to o my supervisor, Dr. Adam Schembri for his help and his guidance. His suggestions, his support and most of all his encouragement throughout these years made the completion of this study possible. o my sign language tutors, Miss R. Zika and Mr. N. Spanos for their help with my many questions on individual manual signs, throughout the challenging task of data transcription. o Dr. Daniel Ezra Johnson for his help and his suggestions during the statistical analysis process using Rbrul o all of my friends from the Modern Greek Studies department who helped me with their support and their detailed comments on an unfamiliar subject o most of all my family, my mother, my father and my brother, who supported me in every possible way. Without them, the whole experience of moving, studying and working abroad would not have been possible.
