Relating to or of the nature of gesticulation; involving or characterized by hand and arm movements.
From Latin 'gesticularis', derived from 'gesticulari' (to gesture with small movements). The suffix '-ar' creates an adjective form emphasizing relation to gestures.
A 'gesticular' person uses their hands so much when talking that you could almost understand them with the sound off—it's why some people are better on video calls than phone calls!
