As for polar questions [Syntax 1.2.1], there are no specific interrogative particles in DGS for content questions. palm_up (one-handed or two handed, with a slight move forward) and index (pointed in a lowered positiontowards the addressee of the question) can occur sentence-finally. As is the case for polar questions, these signs are not obligatory, but rather seem to be used as discourse particles [Lexicon 3.11.3] or as turn-taking signals [Pragmatics 10.2] to indicate that an answer to the question is expected from the interlocutor.
