What has the author D F Spooner written?

There is no author named "D F Spooner." It's likely you are thinking of William Archibald Spooner (1844–1930), an English clergyman and scholar known for a peculiar speech habit: Spoonerisms.

Spoonerisms are verbal errors that involve the transposition of initial sounds or letters in words. These errors were named after Spooner, who is famously believed to have said things like:

* "You have hissed all my mystery lectures." (Instead of "You have missed all my history lectures.")

* "Is the bean dizzy?" (Instead of "Is the dean busy?")

While Spooner himself wrote some academic works, his primary legacy is not as an author, but as a linguistic figure associated with these humorous speech errors.
