Dizzyingly → It is formed from "dizzy" (of uncertain origin, possibly from Middle English *dizzie*, meaning to be in a state of confusion or vertigo) and the suffix "-ingly" (meaning in a manner that). The word "dizzyingly" means in a manner that causes confusion or a spinning sensation.
Think of feeling confused or in a spin ('dizzy') and how doing something in that way ('-ingly') makes it dizzyingly overwhelming.
