The term that Stephen uses for his "nuncle Richie" probably indicates not just familial familiarity but also ridicule. Reference works identify "nuncle" as an obsolete form of "uncle." There is some reason to suppose that it is still occasionally used in Ireland, but the word's Shakespearean associations suggest that Stephen is using it with disrespectful intent.
