Fabulous means extraordinarily good, impressive, or wonderful. When something is fabulous, it stands out as exceptional and remarkable. A fabulous performance in the school play means the actors delivered something truly memorable. A fabulous meal is so delicious that people keep talking about it days later.

The word carries a sense of excitement and admiration. If your friend shows you their science project and you say “That's fabulous!” you're expressing genuine enthusiasm, not just polite approval. Athletes might have a fabulous season when they perform at their absolute best. A teacher might call a student's essay fabulous when it shows creative thinking and excellent writing.

When you have a fabulous time at a birthday party or a fabulous idea for solving a problem, you're describing something that feels special and worth celebrating. The word works for both serious accomplishments and everyday pleasures. A scientist might make a fabulous discovery, while you might simply have a fabulous day at the beach.
