Did you know?

A literary opus is often a single novel, though the word may sometimes refer to all of a writer's works. But opus normally is used for musical works. Mendelssohn's Opus 90 is his Italian Symphony, for example, and Brahms's Op. 77 is his Violin Concerto. Since many composers' works were never given opus numbers in an orderly way, they now often have catalog numbers assigned by later scholars. So Haydn's Symphony No. 104 is Hob.104 (Hob. is short for Anthony van Hoboken, the cataloger), and Mozart's Marriage of Figaro is K.492 (K. stands for Ludwig Köchel).

Word History

Etymology

borrowed from Latin oper-, opus (plural opera) "work, effort, product of labor, work of art," going back to Indo-European *h₃ep-os-, *h₃ep-es- "work" (whence also Sanskrit apas- "work, action"), derivative of *h₃ep- "ability, force," whence Latin op-, *ops "power, ability, wealth, resource(s)," and, with varying suffixation, Sanskrit apnas- "possession, property, work," Hittite happina- "rich," happir-, happar- "business, trade," Germanic *afla- (whence Old English afol "power, might," Old Norse afl "strength"); and, with lengthened ablaut grade, Sanskrit āpas- "work, religious act," Avestan huuāpah- "performing good deeds," Germanic *ōbjan- "to perform" (whence Old Saxon oƀian "to celebrate," Old High German uoben, uoppen "to practice, exercise")

Note: Possibly also related are Old Norse efna "to perform, fulfill," Old English efnan "to accomplish, achieve" (from Germanic *abnjan-?), but this is uncertain.
