Bored vs. Boring: What's the Difference?
Quick Answer
"Bored" is an -ed adjective describing how a person feels — a lack of interest or entertainment (I am bored). "Boring" is an -ing adjective describing the thing, person, or situation that causes that feeling (this movie is boring). The same pattern applies to many other pairs, like interested/interesting and excited/exciting: -ed for the feeler, -ing for the cause.

Common Learner Questions
Does this -ed/-ing rule apply to other adjectives too?
Yes, it's a general pattern in English for adjectives formed from verbs about emotion: tired/tiring, interested/interesting, excited/exciting, confused/confusing, annoyed/annoying, and more. -ed = how someone feels; -ing = what causes the feeling.
Can a person ever be described as "boring"?
Yes — "boring" can describe a person when that person causes boredom in others, as in "He's such a boring speaker." This is different from saying the person themselves feels bored ("He is bored").
Is it wrong to say "I am boring of this"?
Yes, that phrasing is incorrect. Say "I am bored of this" or, more standard, "I am bored with this" or "I am tired of this."
