The deaf population of Martha's Vineyard has fascinated scholars for more than a century since Alexander Graham Bell's research on the frequent occurrence of deafness there and since Groce's book on the island's signing community (Groce, N. E. (1985). "Everyone here spoke sign language: Hereditary deafness on Martha's Vineyard."…

This work categorizes Japanese Sign Language (JSL) toponyms, or place names, and examines factors that potentially affect their structure. Exonyms, influenced by the source Japanese name, and endonyms, independent JSL names, contrast structurally in that exonyms tend to emerge as compounds while endonyms conform more closely to canonical…

The field of language documentation continues to grow, but an historic split between sign language documentation and spoken language documentation persists. In order to fully understand the linguistic context within a community, it can be necessary to overcome this split by designing language documentation projects to address threatened and…

To date, there has not been any research conducted on the South Sudanese Deaf community and South Sudanese Sign Language (SSSL). This article presents an introductory note about both with information gained from personal observations of the authors and from online resources. It provides an insight for furthering extensive research on the newest…

The following article looks into the question of negative affixation in Polish Sign Language. Until today only one negative prefix and one negative suffix were recognized in Polish Sign Language. Our research investigates farther these two affixes looking into their etymologies, constraints and new examples of their use. The negative prefix…

From the point of word formation, the phenomenon of lexical blending is a common productive process, entailing the notion of combination of lexemes in so many languages. In the vast majority of literature on blends, they preserve a linear formation of segments with a shortening of both lexemes. However, in sign languages where morphological…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

This article offers a brief overview of historical linguistics and explores the value of historical "sign" linguistics. The specific focus of the article is on the question of the extent to which the concept of "sign language families" is a legitimate and useful one. It is suggested that although lateral transmission and…

In this article, we provide an overview of the last twenty years of research on Indigenous sign languages, deaf community sign languages, co-speech gesture, and multimodal communication in the Australian context. From a global perspective, research on sign languages and on the gestures that normally accompany speech has been used as the basis for…

In this paper, I discuss methodological and ethical issues that arose in the process of documenting lexical variation in Yucatec Maya Sign Languages (YMSLs). YMSLs are indigenous sign languages used by deaf and hearing people in Yucatec Maya villages with a high incidence of deafness in the peninsula of Yucatán, Mexico. The documentation of rural…

One of the fundamental issues for a language is its capacity to express argument structure unambiguously. This study presents evidence for the emergence and the incremental development of these basic mechanisms in a newly developing language, Central Taurus Sign Language. Our analyses identify universal patterns in both the emergence and…

The current study investigated the mechanism of language switching in unbalanced visual unimodal bilinguals as well as balanced and unbalanced bimodal bilinguals during a picture naming task. All three groups exhibited significant switch costs across two languages, with symmetrical switch cost in balanced bimodal bilinguals and asymmetrical switch…

By providing evidence that sign language is an autonomous language, research has contributed to various changes both within and beyond the signing communities. The aim of this article is to present an example of how sign language change is driven not only by language-internal factors but also by changes in language perception, as well as in the…

This paper presents a critical examination of key concepts in the study of (signed and spoken) language and multimodality. It shows how shifts in conceptual understandings of language use, moving from bilingualism to multilingualism and (trans)languaging, have resulted in the revitalisation of the concept of language repertoires. We discuss key…

In this article, we examine various strategies used to express cardinal numbers in Yucatec Maya Sign Languages (YMSLs) from three historically unrelated communities in Yucatán, Mexico: Chicán, Nohkop, and Cepeda Peraza. Our findings describe some numeral strategies, which remained unattested in previous accounts, and demonstrate that YMSL numerals…
