Calendric Terms

Calendric Terms in Sign Languages

This project aims to document and compare one part of the lexicons of sign languages, the semantic field of time units (like the signs ‘year’, ‘month’, ‘January‘, ‘Friday’ etc.). Its focus is on:
mapping which units in different sign languages are used to express different stretches of time,
how these units are expressed in different sign languages and
what are the linguistic characteristics of these signs (e.g. motivation of the signs and their modifications).

The results of comparative analyses of these data can be used in comparison to what is known about spoken languages, which could aid our understanding of linguistic universals as well as typological generalizations across the whole range of human languages, both signed and spoken.

This project partially follows  New Sign Language Typology Project of prof. Ulrike Zeshan et al. (iSLanDs, International Institute for Sign Languages and Deaf Studies in Preston, UK), in which we found a valuable inspiration.  Also, we are very much obliged to Ulrike Zeshan and Keiko Sagara for helping us to organize this project.

August 2016: We are very happy to announce that we have received data from sign languages of Iceland, Mexico and Jordan.

2/11 2016: Great!!! We have received data from Russian, Swedish, Israeli and Chinese Sign Languages.

2017: So far it has been quite a busy year; we have been working on the summary of what happened during the year.
We have received data from Japanese, Cambodian, Slovak and Argentine Sign Languages, more data are expected from Austrian and other Sign Languages, and of course we have been working on the volume.
Thanks to everybody for participation!
