Here's why "great" might sometimes seem surprising:
* Unexpectedly positive: If someone uses "great" to describe something you weren't expecting to be good, it can feel surprising and delightful. For example, if you're worried about a presentation and your boss says "Great job!" it's a pleasant surprise.
* Overused: "Great" is a very common word, often used casually. When it's overused, it can lose its impact and feel less impactful, even when used sincerely. In this case, it might feel like a surprise if someone actually means it when they say "great."
Here are some words that are typically used to express surprise:
* Wow!
* Amazing!
* Really?
* You're kidding!
* Oh my gosh!
So, while "great" can sometimes be surprising in context, it's not a word typically associated with surprise in general.
