Here Blount tells a story of a boy and his father riding on a horse out of London. The boy, having grown up in the city, knows nothing of the countryside, and asks his father what kind of noise a horse makes. His father explains that the horse 'neighs'. Riding further, the boy hears a cock crow and says 'doth the cock neigh too?' Because of this silly mistake, the boy becomes nicknamed 'cock-neigh'. Blount uses this story to show one possible origin of the word Cockney.
This page also defines the word coffa or cauphe described as 'a kind of drink among the Turks and Persians, (and of late introduced among us) which is black, thick and bitter...' This is an early spelling for the word coffee.
