Why this word is great

VANILOQUENCE — [Noun] Idle or vain talk. From Latin vanus ("vain") + loquentia ("talk"). Unlike "soliloquy" (a speech to oneself, often dramatic) or "ventriloquism" (the illusion of displaced speech), vaniloquence is the hollow performance of words without substance. It is the politician's rehearsed platitudes dissolving into static, the influencer's scripted sincerity echoing in an empty room, or the dinner party guest who speaks at length but says nothing—a reminder that language, for all its power, can also be the thinnest veneer over silence.

noun

Idle or vain talk.“In philosophy, however, it is to be deplored that eloquence too commonly passes for science, being mistaken for logical acquirement; but truth alone is the just eloquence of philosophy, and without it the finest composition is, to the logician, but babbling and vaniloquence.”
