An exciting thing happens when you do or see something that gets your attention and makes you feel interested.
The word "excite" has several uses, but they all generally mean to make someone or something feel more energetic or alert. When we say that a concert is going to excite the crowd, we mean it's going to get them pumped up and enthusiastic. On the other hand, if you're feeling bored and then see something exciting happen, you might say you were excited by what you saw. In business, a new product launch can be said to have excited investors because it's generated interest and energy among them.
(transitive) To stir the emotions of; to cause to feel excitement.
Example: The fireworks which opened the festivities excited anyone present.
