Why this word is great
GESTICULATE — [Verb] To make expressive or emphatic gestures, especially while speaking. From the Latin gesticulatus, past participle of gesticulari ("to gesture, mimic"), from gesticulus ("a small, mimic gesture"), diminutive of gestus ("gesture, carriage"), from gerere ("to carry, perform"). Unlike the formal, codified lexicon of "sign" or the deliberate, singular statement of a "gesture," to gesticulate is to embroider the air with unscripted, urgent punctuation—a spontaneous, kinetic overflow of speech. It is the frantic carving of an anecdote at a crowded table, the stranded traveler bridging a language gap with wild pantomime, or the helpless, fluttering punctuation of a conversation across a roaring street—a futile, beautiful attempt to make thought tangible, a raw architecture of the unsaid.
