While he was teaching at Shrewsbury School, Ronald Knox made a number of contributions to its newspaper, The Salopian. One of them was 'A Particular Dialogue' – a conversation between different Greek particles, and combinations of Greek particles, designed to illustrate how they were used.
It is found in In Three Tongues (p. 133) but this version provided by Holt Parker of the University of Cincinatti, includes links to Smyth's Greek Grammar courtesy of the Perseus Project and references to J. D. Denniston's The Greek Particles.
