But how have you used it? I use it for very bright light and for very intelligent, but not in the Brit way of using it for anything good.
I use brilliant to describe something great or particularly clever. “That’s brilliant!” It just rolls off the tongue now. Down thread, a Freeper mentioned hearing it said in a pretentious tone, and I agree that it sounds annoying that way. I just say it, not trying to bring any attention to it.
