I love the way the British use the word "brilliant." It doesn't sound as sophomoric as "awesome" or as cliched as "amazing." It's actually one of things I miss most about England. Hearing those wonderful, soft tones. When I came back to the States, I appreciated the accents here as well, as they seemed new and familiar at the same time.
Brilliant. Can mean on key, on top, bright, enlightened, sparkling. And brilliant feels like the a beautiful string of notes on a xylophone.
What's your favorite word to hear in an accent?
