Sign Language Science: How Signed Languages Evolve and Change

Have you ever wondered how signed languages develop their complex structures, or how they adapt and change naturally over time? Like spoken languages, signed languages are living systems that evolve through historical use, community interaction, and cultural shifts. This text-based course guides you through the scientific study of sign language evolution, helping you transition from understanding basic linguistic definitions to analyzing how manual gestures transform into structured, rule-governed grammatical systems across generations. What you will learn: - Understand the foundational principles of sign language linguistics; - Trace the historical evolution of sign languages from early gestural roots; - Analyze the natural factors that drive language change, including articulation and clarity; - Explore how modern researchers use digital sign language corpora to track linguistic shifts; - Examine the role of sociolinguistic variation and community structure in shaping sign vocabulary. You will start by exploring core terminology and fundamental concepts of sign structures before examining historical case studies of language change. This course is designed for beginners, students of linguistics, and anyone curious about the science of sign languages, with no prior background required. Start reading today to uncover the fascinating science behind how signed languages grow, adapt, and thrive.
