ESQUIREn. Formerly a dignity immediately below that of a knight; now a dignity immediately above that of a felon. In this country the only allowable use of the word is, in its abbreviated form, in the superscriptions of letters: but ignorant and vulgar writers attach it to the names of prominent men as a title of respect. Mr. Frank Pixley, of the Argonaut, uses it thus, but with commendable discrimination — he appends it only to the names of the rich.
