The term “imperative” refers to a sentence type with a special form. This form may differ from the forms of other sentence types in the presence of special imperative markers, a difference in word order, presence/absence of certain kinds of subject, verb morphology, and special negative forms. An imperative sentence may be used for a variety of functions but the most typical function of an imperative is commands that are used to give orders such as ‘Give me the book!’. Other functions of imperatives are invitations, suggestions, permissions, instructions, and recommendations. The following subsections describe how imperatives are used to express these functions as well as what marks a sentence as an imperative in TİD.
A combination of manual and non-manual features are used: head tilt, eye gaze towards the addressee, verb articulated with a higher degree of intensity and a shorter duration perceived as abrupt, and optionally but frequently a sentence-final palm-up.
