In particular, we base our discussion on the mouthing that appears in interrogative constructions in naturalistic data. Our findings include that mouthing varies in both morphology and syntactic distribution. Some can be part of sign words and some can function as question markers. In conclusion, we argue that mouthing basically belongs to CSL grammar, rather than that it is a code-mixing phenomenon ER -
