Agreed.Another pair of expressions that natives take for granted. Some context would have helped, but in my understanding:
"... not a little ..." means more than "a little" and could indeed mean "a lot". I don't think it could mean less than "a little?
"... not a bit ..." means none.
Another example of the confusing things that natives take for granted.
I can't answer that question because the response "No, not a little," just does not make sense in the context. It is not something a native speaker would say and I can't associate any meaning with it.If there are sentences like following:
——There is a little bread here I think.
——No, not a little.
then what does not a little mean? both much and none?
