Gesticulation
noun
a gesture, esp. a dramatic one, used instead of speaking or to emphasize one’s words.
“Nor did I at first understand that the gesticulations of a curious-looking object, in a cut-away coat and evening shirt, were aimed at me.”
Paragraph 3 sentence 3 in A Room of One’s Own by Virginia Woolf
Now that I understand this word, I understand that he was making outraged gestures at her because she didn’t belong on the turf, it was for men only.
