Tactile sign languages are generally developed from a pre-existing sign language present in institutional contexts. In this article, we explore the emergence of a sign language within a family context of three deaf siblings in which one of them is deafblind, aiming at analyzing the adaptations made from the visual (sighted) familiar sign language to the tactile mode, that enabled the maintenance of the communication among them. The results of the adaptations of pronouns and fingerspelling carried out in the transition from a visual to a tactile system point to innovations that partly align with the assumptions found in the literature. However, since this is not an institutional sign language, there is less dependence on the visual system and greater flexibility in grammatical innovation.
Keywords: Emerging sign language. Tactile sign language. Linguistic emergence. Interrogative pronouns. Fingerspelling.
