The movie far surpassed expectations. It was superb. That 5-star hotel? Also superb. Anything that goes beyond being great can be called superb.
Start by noticing that superb contains super, and you're more than halfway to remembering its meaning. The only real difference between super and superb (besides the letter "b") is that something superb is surprisingly or especially excellent. A taco that tastes great might be super. But if it's among the very best tacos you've ever eaten, it's superb. Dinner tonight? Super! How was dinner? It was superb!
