- There are some who find the figurative noun sense problematic, 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".)

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