"impending" & "upcoming", "coaster" & "saucer".
1. "impending" & "upcoming". Both of them mean sth. is gonna happen, it seems like that "impending" normally means something bad, like "impending doom", "impending disaster", "impending bankruptcy", etc.. Is that ture?
2. "coaster" & "saucer". Both of them, I think, are small plates or that sort of thing put under cups. Is "saucer" bigger than "coaster"?
