Usage

The phrasal verb impact on, as in when produce is lost, it always impacts on the bottom line, has been in the language since the 1960s. Many people disapprove of it, saying that make an impact on or other equivalent wordings should be used instead. This may be partly because, in general, new formations of verbs from nouns (as in the case of impact, action, and task) are regarded as somehow inferior; in addition, since the verbal use of impact is associated with business and commercial writing, it has the unenviable status of ‘jargon’, which makes it doubly disliked. Compare with enthuse

Origin

Early 17th century (as a verb in the sense 'press closely, fix firmly'): from Latin impact- 'driven in', from the verb impingere (see impinge).

impinge from mid 16th century:
The word impinge is from Latin impingere ‘drive something in or at’, from in- ‘into’ and pangere ‘fix, drive’. The word originally meant ‘thrust at forcibly’. Impact (early 17th century) comes from the past form of the same source.

Rhymes

abreact, abstract, act, attract, bract, compact, contract, counteract, diffract, enact, exact, extract, fact, humpbacked, interact, matter-of-fact, pact, protract, redact, refract, retroact, subcontract, subtract, tact, tract, transact, unbacked, underact, untracked
