Intensive marking shows that a state or activity is experienced as more intense than usual. NGT employs puffed cheeks and blowing out air for marking intensity, and this non-manual can combine with adjectives and verbs. The following video from the Corpus NGT shows the non-manual marker of puffed cheeks accompanying the constituent very tired โ and also clearly shows interaction between the cheeks and the mouthings [oeh] โoehโ and [moe] โtiredโ: since the mouthings are articulated simultaneously with the manual elements, the intensive markers appear more-or-less in the middle of the constituent and after it, and hardly accompany the manual elements. This interaction can occur when non-manual markers are articulated by the mouth, tongue or cheeks, and is not restricted to the intensive; it is also observed with markers of the diminutive and augmentative (MORPHOLOGY 2.2.1).
Video a. The constituent 'very tired', marked by non-manuals (CNGT0208, S11, 08:01.005-08:02.815).
