I loathe -- despise, scorn, spurn -- the relatively new verb 'to impact'. I didn't like it when it was new, way back some time in the late 1980s, and I haven't got any fonder since.
Even less do I like this formulation, in a new book about refrigeration: 'Chapter Six considers how the machine has impacted on food consumption...'. IMPACTED ON. In what god-forsaken universe is that English?? As my high school friend Laura would have said: 'Oh, barf!'. I'm more refined, so I'll simply say: Good lord. It's as if the words 'affected', 'changed', or 'irrevocably altered' don't exist. But wait -- they do!
