Usage notesEdit

  • Adjectives often applied to "impact": social, political, physical, positive, negative, good, bad, beneficial, harmful, significant, great, important, strong, big, small, real, huge, likely, actual, potential, devastating, disastrous, true, primary.
  • The adposition generally used with "impact" is "on" (such as in last example in section above)
  • There are English speakers who are so averse to the verb sense that they have become hypersensitive to the use of the figurative noun sense, with a low threshold for labeling such use as overuse (cliché). In defensive editing, the solution is to replace the figurative noun sense with effect and the verb sense with affect, which nearly always produces an acceptable result. (Rarely, a phrase such as "the impact of late effects" is better stetted to avoid "the effect of [...] effects".)

Usage notesEdit

Some authorities object to the verb sense of impact meaning "to influence; to affect; to have an impact on". Although most verbification instances in English draw no prescriptive attention, a few do, including this one. To avoid annoying those readers who care, one can replace the verb sense with affect, which nearly always produces an acceptable result. See also the usage note for the noun sense.
