Usage Note: The use of impinge meaning "to encroach; trespass," as in Americans dislike any policy that impinges on their liberty, is well established as standard. However, when impinge is used more loosely to mean "to have an effect" the Usage Panel is split. In our 2001 survey, only 47 percent of the Panel found the following sentence to be acceptable: What the recovered diary revealed about the villagers directly impinged on the lives of people living there many years later.
