/ˈtɹɪləd͡ʒi/
Etymology
PIE word *tréyes Learned borrowing from Latin trilogia, itself borrowed from Ancient Greek τριλογία (trilogía, “trilogy”). Morphologically from tri- + -logy.
noun
- A set of three connected works—usually dramas, literary pieces, films, or musical compositions—all related by theme, characters, or setting.“That such a safe adaptation could come of The Hunger Games speaks more to the trilogy’s commercial ascent than the book’s actual content, which is audacious and savvy in its dark calculations.”
