The phonology of NGT does not only comprise manual elements, but also non-manual elements. Non-manuals are (linguistic) elements expressed through the torso, shoulders, head and face. In the current sub-chapter, only non-manuals that are part of lexical signs are discussed (see, for example, Morphology, Section 3.5.1, for a description of mouth gestures with an adverbial function). Special attention is paid to mouth actions, divided into mouth gestures (PHONOLOGY 1.5.1) and mouthings (PHONOLOGY 1.5.2). Other non-manual elements, such as wide-open eyes for the expression of surprise, are described in PHONOLOGY 1.5.3.
