Etymology: 1775–85; back formation from impacted usage: The verb impact has developed the transitive sense “to have an impact or effect on” (The new reading program has impacted the elementary schools favorably) and the intransitive sense “to have an impact or effect” (Our work here impacts on every department in the company) These uses, though common, are often harshly criticized.
