- spoonerism
- 1900, but perhaps as early as 1885, involuntary transposition of sounds in two or more words (cf. "a well-boiled icicle" for "a well-oiled bicycle;" "scoop of boy trouts" for "troop of Boy Scouts"), in allusion to the Rev. William A. Spooner (1844-1930), warden of New College, Oxford, who was famous for such mistakes.
