A spoonerism is an occurrence of speech in which corresponding consonants, vowels, or morphemes are switched (see metathesis) between two words of a phrase.
An article in The Times from that year reports that: The boys of Aldro School, Eastbourne, ... have been set the following task for the holidays: Discover and write down something about: The Old Lady of Threadneedle-street, a Spoonerism, a Busman's Holiday...[9] An article in the Daily Herald in 1928 reported spoonerisms to be a "legend".
[10] In 1937, The Times quoted a detective describing a man as "a bricklabourer's layer" and used "Police Court Spoonerism" as the headline.
I grew up loving Ronnie Barker and can only hope the news that I am to give a talk in his name doesn’t leave him spitting spiritedly splenetic spoonerisms in comedy heaven.
[36]: p.78 As complements to spoonerism, Douglas Hofstadter used the nonce words kniferism and forkerism to refer to changing, respectively, the vowels or the final consonants of two syllables, giving them a new meaning.
[37] Examples of so-called kniferisms include a British television newsreader once referring to the police at a crime scene removing a 'hypodeemic nerdle'; a television announcer once saying that "All the world was thrilled by the marriage of the Duck and Doochess of Windsor";[38] and during a live radio broadcast in 1931, radio presenter Harry von Zell accidentally mispronouncing US President Herbert Hoover's name as "Hoobert Heever".
