Question: Don Carlos and Candide, are operas?

Documents:
source: Don Carlos
text: Don Carlos Don Carlos is a five-act grand opera composed by Giuseppe Verdi to a French-language libretto by Joseph Méry and Camille du Locle, based on the dramatic play "Don Carlos, Infant von Spanien" ("Don Carlos, Infante of Spain") by Friedrich Schiller. The opera is usually performed in an Italian translation. In addition, it has been noted by David Kimball that the Fontainebleau scene and auto da fé "were the most substantial of several incidents borrowed from a contemporary play on Philip II by Eugène Cormon".

source: Candide (operetta)
text: Candide (operetta) Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire. The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel. The primary lyricist was the poet Richard Wilbur. Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself. Maurice Peress and Hershy Kay contributed orchestrations. Although unsuccessful at its premiere, "Candide" has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity. It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.
