An average English word is four letters and a half. By hard, honest labor I've dug all the large words out of my vocabulary and shaved it down till the average is three and a half.... I never write "metropolis" for seven cents, because I can get the same money for "city." I never write "policeman," because I can get the same price for "cop." ... I never write "valetudinarian" at all, for not even hunger and wretchedness can humble me to the point where I will do a word like that for seven cents; I wouldn't do it for fifteen.
