There are a great many gradations between words of everyday use and such as are not at all understood by the common people, and to the latter class may sometimes belong words which literary people would think familiar to everybody. Hyde Clark relates an anecdote of a clergyman who blamed a brother preacher for using the word felicity, “I do not think all your hearers understood it; I should say happiness.” “I can hardly think,” said the other, “that any one does not know what felicity means, and we will ask this ploughman near us. Come hither, my man! you have been at church and heard the sermon; you heard me speak of felicity; do you know what it means?” “Ees, sir!” “Well, what does felicity mean?” “Summut in the inside of a pig, but I can’t say altogether what.”
