Origin of impact

First recorded in 1775–85; (noun and v.) back formation from impacted
The verb impact has developed the transitive sense “to have an impact or effect on” ( The structured reading program has done more to impact the elementary schools than any other single factor ) and the intransitive sense “to have an impact or effect” ( The work done at the computer center will impact on the economy of Illinois and the nation ). Although recent, the new uses are entirely standard and most likely to occur in formal speech and writing. See also impactful.
