Is impact a verb?

Verb

You may occasionally run into claims that impact is not a verb, or that it is somehow ill-suited to a role in this part of speech. Not only is that not the case, but the verb form of impact is much older than the noun form. It is possible that the word started attracting more displeasure when it began being widely used in a figurative sense as a transitive verb ("we expect the recession to impact the company"). The word is certainly a verb, although before using it in this manner in writing it is worth considering your audience, and whether members of it are likely to consider this use problematic.
