This workshop examines the linguistic, cultural, and identity-based distinctions between American Sign Language (ASL) and Puerto Rican Sign Language (LSPR). Although both languages may appear similar, LSPR includes unique features such as the strong integration of Spanish-influenced mouth movements that shape meaning and communication style. Participants will explore why Deaf Interpreters must develop competence in LSPR to provide accurate, culturally responsive interpreting and to avoid assumptions that ASL alone can meet the needs of the Puerto Rican Deaf community.
