opus Meaning
- formal
- literary
An "opus" is a creative work, most commonly used to refer to a musical composition or a literary masterpiece. The word carries a sense of weight and significance, suggesting that the work is a substantial contribution to an artist's body of work or a defining achievement in their career. While it can refer to any individual work, it is often used in the context of an "opus magnum" (or "magnum opus"), which signifies a person's greatest or most important work. Because of this, the term is rarely used for trivial or casual projects; it implies a level of ambition, scale, or artistic maturity that commands respect.
