Gesticulate comes from Latin gesticulatus, past participle of gesticulari ('to gesture'), from gesticulus, diminutive of gestus ('gesture'), from gerere ('to carry, bear, perform'). The participial history matters: an older verbal form is preserved as an English adjective or derivative, so the modern word keeps the result of an action as its lexical shape. In present use, it is used as a verb meaning "to make expressive gestures with the hands and arms while speaking", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as gesticulated, gesticulating, gesticulation, gesticulator, and gesticulative and related forms such as gesture and gest, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin gesticulari and Latin gerere, keeping the history tied to concrete forms rather than a loose resemblance.
