affectedly

1614, Thomas Lodge (translator), The Workes of Lucius Annæus Seneca, London: William Stansby, Epistles to Lucilius, Epist. 115, p. 463, The speech is the Image of the minde: if a man mince it, disguise and polish it ouer curiously, it is a signe that he which speaketh it, is an hypocrite, and little worth. It is no manly ornament to speake affectedly.

1628, John Earle, Micro-cosmographie, or, A Peece of the World Discovered; in Essayes and Characters, London: Edward Blount, 55. “A stayed Man,” One not hasty to pursue the new Fashion, nor yet affectedly true to his old round Breeches.
