Racketeering comes from racketeer (racket + -eer) + -ing; racket in the sense 'fraudulent scheme' is of uncertain origin, perhaps from the earlier sense 'noise, din', itself probably imitative. Older glosses in the chain include "fraudulent scheme" and "noise, din", which help explain the semantic range of the modern word. Morphologically, racketeering is best read as compound, suffixal formation, imitative formation, and uncertain formation, yielding an English noun shaped by both form history and later usage. In current English it functions as a noun, with the sense "the running of an illegal business or fraudulent scheme for profit". related forms include racket and racketeer. The result is an English noun whose etymology preserves the older forms while supporting the word's specialized modern meaning.
