apostrofly
n.— «There is no guarantee that the apostrophe will appear in the right place in Queens’ College, Cambridge. The apostrophe, it sometimes seems, is like an insect—an apostrofly—over the dining table, alighting where it will. If either name, Queen’s or Queens,” appears in the corrections column a dozen readers will accuse me of having an Oxbridge fixation.» —“Open door—It’s in its rightful place—The readers’ editor on …the plague of the apostrofly” by Ian Mayes Guardian (U.K.) Sept. 30, 2002.
