Ok, I think I have it now.
Rose, but not a flower.
White, but not clean.
Mad, but not insane.
Dream, but not that thing you do while asleep.
Fire, but not a flame.
Dress, but not a piece of clothing.
Nerd, but not geek.
Glasses, but not cups.
Bowl, but not a dish.
Bill, but not Clinton.
Bush, but not George.
Tea, but not something that is almost, but not quite, entirely unlike coffee.
