British Sign Language (BSL) is the language used by the deaf community in the UK. In this chapter, we describe sociolinguistic variation and change in BSL varieties in England. We show how factors that drive sociolinguistic variation and change in both spoken and signed language communities are broadly similar. Social factors include, for example, a signer’s age group, region of origin, gender, ethnicity and socio-economic status. Linguistic factors include assimilation and co-articulation effects. Some other factors, such as age of acquisition, however, appear unique to signing communities. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
