Polar interrogatives in DGS are most of the time accompanied by raised eyebrows, head forward position and sometimes by a slight forward body lean. These non-manual elements are used throughout the whole sentence, as shown in example a. Further possible non-manual markers in these types of sentences are furrowed eyebrows over the whole phrase, semantically adding a notion of disbelief or surprise to the question (example b). This non-manual marking is also used to clarify, whether something was correctly understood or not.
