What is the meaning of "nothing could be less like ..." structure? Sometimes I see it with a "than", and other times without "than".
Say this example -
Nothing could be less like A
If we go by the literal meaning, it means to me that everything is similar to A. Am I right?
Nothing could be less like A than B
Here also it means that everything is similar to A, instead of B
Am I right on the assumption? If not please tell me the meaning and explain how it comes, because if literal meaning is accepted, the meaning I suggested above is going to be true. Or is this construction an idiom?
