Thirty years ago it was the use of tương tác as a verb, but opposition lớn that khung has more or less disappeared, and attention now focuses on the verbal use of impact meaning "have sầu an effect, affect." Eighty-four percent of the Usage Panel disapproves of the construction khổng lồ impact on, as in the phrase social pathologies, common to the inner thành phố, that impact heavily on such a community; and fully 95 percent disapproves of the use of impact as a transitive verb in the sentence Companies have used disposable techniques that have sầu a potential for impacting our health. But even these figures vì not reflect the degree of distaste with which critics view the usage: in their comments some Panelists labeled the usage as "bureaucratic,""pretentious,""vile," & "a vulgarism." It may be that the particular pretentiousness associated with the verbal use of impact is caused by its derivation from an already questionable metaphoric use of the noun impact, as in phrases such as the political impact of the decision or the impact of the program on the community, in which no more is usually meant than might have sầu been expressed by effects or consequences. But though impact may have begun life a generation ago as an inflated substitute for "affect significantly," it has by now become so comtháng in corporate and institutional contexts that younger speakers appear to regard it as wholly standard & straightforward usage. Within a few years, accordingly, the usage is likely lớn be no more objectionable than tương tác is now, since it will no longer betray any particular pretentiousness on the part of those who use it.Word History: The often criticized use of impact, as in the passage "social pathologies, common to lớn the inner thành phố, that impact heavily on such a community," illustrates how one part of speech can have an impact on another part of speech spelled the same way. The usage also reflects the role played by science in the formation of new senses of words. The noun impact comes from the past participle impāctus of the Latin verb impingere, which means "lớn bring into lớn violent tương tác,""to lớn drive persons or other creatures onlớn or against," & "khổng lồ fix, fasten onto." Our noun, first recorded in 1781, derived its sense from the "contact" sense of impingere. First recorded in a scientific context having to lớn do with the collision of bodies, it was much used in scientific contexts & later, in the 19th century, took on a figurative sense, "the effect of one thing upon another." The verb impact, on the other hand, also coming from Latin impāctus, is found much earlier than the noun, that is, it is first recorded in 1601, deriving its sense from the "driving" and "fixing" senses of impingere and meaning "khổng lồ press closely inlớn something, paông chồng in." This old sense is still with us, but the later noun had an influence on the verb, giving us senses such as "to strike forcefully" và "to lớn have sầu an effect."
