Sign Language Linguistics is the study of the structure and use of sign languages, which are visual languages used by the Deaf community. It examines how signs are formed, how they convey meaning, and how they are organized into larger units like phrases and sentences. Researchers in this field analyze various aspects of sign languages, including phonology, morphology, and syntax. They also explore how sign languages differ from spoken languages and how they develop within different cultures, contributing to our understanding of human language as a whole.
