Chapter 4. Linguistic study
The present chapter offers a brief overview of the main linguistic studies investigating LIS. Specifically, the first section (SOCIO-HISTORICAL BACKGROUND 4.1) provides a description of the phonological, morphological, syntactic and pragmatic structures of LIS, comparing their analyses and contributions to the investigation of LIS. The second section (SOCIO-HISTORICAL BACKGROUND 4.2) deals with lexicographic works hinting to some related issues. The third section (SOCIO-HISTORICAL BACKGROUND 4.3) contains a description of corpora and data collected in the last few decades on LIS. The last section (SOCIO-HISTORICAL BACKGROUND 4.4) of this chapter concerns studies on socio-linguistic and diachronic variation of LIS, considering Deaf education, age, gender, and socio-economic background as socio-linguistic factors.
