Is it ensure, insure, or assure?
song on a convivial theme composed usually for singing in accompaniment to drinking. The form became a standard element in certain types of 19th-century opera and operetta, frequently involving not only a soloist but also a chorus joining in with choral repeats or refrains. In Italy the drinking song is known as brindisi (Italian: "toast"). In Giuseppe Verdi's operas drinking songs range from the cheerful "Libiamo" ("Let Us Drink") in La traviata (1853), to Iago's foreboding toast in Otello (1887).
