trite
Boring and unoriginal because it has been used too much.
Trite means boring and unoriginal because it's been used too many times before. When something is trite, it was probably fresh and interesting once, but now it feels stale and predictable.
Imagine reading a story that starts with “It was a dark and stormy night.” That opening was exciting when writers first used it, but now it's so overused that it makes readers groan. Or picture someone offering advice like “Just be yourself!” when you're nervous about making friends. The advice might be true, but it's so worn out that it doesn't feel very helpful anymore.
Trite phrases are sometimes called clichés. “Every cloud has a silver lining” and “Practice makes perfect” are trite sayings because we've all heard them a thousand times. The words lose their power through repetition, like a path worn bare from too many footsteps.
Writers work hard to avoid trite expressions because readers want fresh, original ideas. When you're writing a story or essay, you can try to express your thoughts in your own words rather than reaching for tired phrases you've heard before. The goal is to say something real that makes people think or feel something new.
