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).

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 despite its relative frequency, saying that make an impact on or other equivalent wordings should be used instead. New formations of verbs from nouns (as in the case of impact) are often regarded as somehow inferior.
