Still image samples illustrating the two types of violations in the DGS sentences. Notations in lowercase indicate the location of the sign: a = right of the signer; b = left of the signer; c = in front of the signer; 1 = signer; POINT = pointing to a location to place the referent in the signing space; the errors are marked through dotted lines resp. bold prints 1a) correct sentence: the verb sign NEEDLE moves correctly from the subject location to the object location; 1b) morphosyntactically incorrect sentence: the verb sign NEEDLE moves incorrectly from an unspecified location in front of the signer to the signer indicating first person; 1c) semantically incorrect sentence: semantically implausible object sign COAT.
