This study investigates the linguistic practices of the queer community in Delta State, Nigeria, focusing on the morph-semantic features of its language. Using qualitative methods including interviews, questionnaires, focus group discussions, and WhatsApp chat analysis the research identifies lexical items peculiar to the LGBT community and examines the processes of word formation and semantic variation. Drawing on Laurie Bauer’s morphological productivity theory, the study uncovers innovative morphological structures and semantic shifts reflecting identity, secrecy, and solidarity. Findings reveal that queer language in Delta State exhibits high morphological productivity, incorporating affixation, clipping, compounding, and borrowing. Many lexical items have no direct equivalents in Standard English and exhibit meanings accessible only to insiders. The research underscores the intersection of language, identity, and marginalization in sociolinguistic discourse and contributes to the documentation of underexplored Nigerian linguistic varieties.
