CODA’s heritage sign language in Spain

Abstract

Highlights: - Study explores family, education challenges in heritage sign languages (SL) acquisition for children of deaf adults (CODAs). - Interviews highlight CODAs' insights on SL learning in family and community contexts. - Deaf community interaction fosters standard SL skills, reinforcing cultural identity. - Intrafamilial dynamics often lead to bimodal communication, influencing SL transmission. - Formal SL education aids CODAs, but many start with insecurity despite prior exposure.
