What is the origin of epistolary?
English epistolary comes from the Latin adjective epistulāris (also epistolāris), a derivative of the noun epistula (epistola) “a letter, a dispatch, a written communication, an epistle (as in the New Testament).” Epistula comes from Greek epistolḗ, which has the same meanings. An epistolary novel is one that is composed in a series of documents, usually (private) letters, but also diary entries, newspaper articles, and other documents. Such novels were especially popular in the 18th century, e.g., in England, Pamela by Samuel Richardson (1740); in France, Dangerous Liaisons by Pierre Choderlos de Laclos (1782); and in Germany, The Sorrows of Young Werther by Johann Wolfgang von Goethe (1774). Bram Stoker’s epistolary novel Dracula, published in 1897, and continuously in print ever since, has attained a kind of immortality. Epistolary entered English in the 17th century.
