1.3.2.2. Non-manual markers

We indicated specific non-manual markers for the various types of imperatives in SYNTAX 1.3.1.  The spreading domain of non-manual markers refers to their extension over the manual signs they co-occur with. The non-manual markers for the imperative are not limited to the signs palm_up or movimp (when it is present), but extend over the verb and its arguments. Although non-manual markers are subject to individual variations (possibly being influenced by emotive facial expressions that commonly occur with imperative sentences), a marked facial expression is always found in the imperative.
