On the subject of one word titles (see below), it is, I think, worth mentioning the late English novelist Henry Green, who frequently went for the short, sharp option. Amongst his various book-titles we find: Doting, Loving, Living, Nothing, Blindness, Caught and Concluding. One imagines that Nothing might have been a hard sell.
‘I’ve just written a book’.
‘Oh yes, what is it called?’
(end of conversation).
We might also consider the work of the novelist Chem Kosgey, who names all of his books after animal noises. Quack was published in 1995, followed shortly by Moo (1997) Meow (2001) and, peculiarly, Rfffk (2005).
