Background of the study
Nigerian Sign Language (NSL) serves as the primary mode of communication for the Deaf community in Nigeria, particularly in urban centers like Lagos. The morphological processes in NSL—such as compounding, inflection, and derivation—are essential for conveying complex ideas and social nuances. This study examines these morphological processes to understand how NSL evolves and adapts to meet the communicative needs of its users (Adewale, 2023). Through detailed analysis of sign recordings and interviews with Deaf individuals, the research documents how new signs are formed, how existing signs are modified, and how morphological structures facilitate effective communication within the community. The study highlights the interplay between traditional sign formation and contemporary influences, such as technology and increased social interaction. It also explores the role of NSL morphology in cultural identity and educational outcomes, providing valuable insights for language planning and policy formulation for Deaf communities (Ojo, 2024; Uche, 2025).
Statement of the problem
Despite its importance, Nigerian Sign Language has received limited scholarly attention, particularly regarding its morphological processes. The dynamic nature of sign formation in NSL is not well documented, leading to gaps in understanding how morphological innovations contribute to communication and cultural identity among Deaf individuals (Adewale, 2023). This lack of research hampers efforts to develop effective educational resources and language policies that support NSL. Addressing this deficiency is crucial for fostering inclusivity and ensuring that the linguistic needs of the Deaf community are met. This study aims to fill the gap by systematically examining the morphological processes in NSL within Lagos (Ojo, 2024).
Objectives of the study:
1. To document morphological processes in Nigerian Sign Language.
2. To analyze how new signs are formed and modified.
3. To assess the impact of these processes on communication and cultural identity.
Research questions:
1. What morphological processes are evident in NSL?
2. How do these processes facilitate effective communication?
3. What are the implications for language policy in Deaf communities?
Significance of the study
This study is significant as it provides a comprehensive examination of the morphological processes in Nigerian Sign Language, offering insights that can enhance educational practices and policy development for Deaf communities. The findings will benefit linguists, educators, and policymakers by promoting inclusivity and linguistic preservation (Uche, 2025).
Scope and limitations of the study:
The study focuses exclusively on morphological processes in Nigerian Sign Language as used by Deaf communities in Lagos. It does not extend to other aspects of NSL or other regions.
Definitions of terms:
1. Morphological Processes: The mechanisms by which words or signs are formed and modified.
2. Nigerian Sign Language (NSL): The primary sign language used by the Deaf community in Nigeria.
3. Deaf Communities: Groups of individuals who use sign language as their main form of communication.
