But first, let's learn about soup

Separated by a Common Language will teach you about the differences between American and British conceptions of soup.

It turns out that chunks are important.

These are not the definitions of soup, but the core exemplars of what belongs to the SOUP category, from which the 'soupiness' of other foods is measured. So, each culture has soups that don't conform to these ideals, but they nevertheless have enough in common with them (e.g. being liquid, considered food rather than drink, containing vegetables) to also be called soup. The differences in the prototypes might have some effects on the boundaries of the category.
