Did you know?

You may recognize magnum (meaning "great") as a Latin word that shows up in altered forms in several English words, and perhaps you can also come up with a few words that are related to opus ("work"). Magnitude, magnanimous, opulent, and operate are some obvious relations of the two. Magnum opus, which entered English in the 18th century, retains the original Latin spelling and the literal meaning "great work." Although the term most often refers to literary, musical, or artistic productions, it has been used to describe many kinds of great works, including games, construction projects, and even surgical techniques.
