Motion On Its Own

 Ngo, Hood, Martin, Painter, Smith & Zappavigna (2022: 32-3):

Motion can also occur on its own, without a hand shape concurring with an entity. For example, the vlogger uses a circular hand motion (two rotations) concurrent with the tone group //1 tried washing it / out it’s //.

This is recycled verbatim from Martin & Zappavigna (2019). Here are the comments from the review of Martin & Zappavigna (2019): Failing To Account For Body Language Meaning.

To be clear, the hand is always shaped in some way. The semiotic question is whether or not the shape means something other than itself.  

The authors' (unsupported) declaration that handshapes "concur" with linguistic elements ("entities") ignores the meaning of all the handshapes that violate that stipulation, such as those depicted in [(74)].  

So in this instance, the authors' failure to identify body language meaning is presented, instead, as just one way that the body language system works.
