The sign language commonly used by the Deaf community in Haiti is currently reported as a dialect of ASL, but many regard it as a separate language, as there are significant lexical and grammatical differences and challenges to mutual-intelligibility. ASL tends to be used in schools and with foreigners, which has hidden the separate existence of LSH from outsiders (Hochgesang and McAuliff 2016).
