Comments are divided into <em>comment types</em>, which are the entity sub-types for the comment entity type. Each comment type has its own fields and its own form and display settings; each type can be used to comment on a single entity type. You can set up different comment types for different commenting purposes on your web site; for example, you might set up a comment type for recipes that has fields "How did it taste?" and "Did the instructions work?", and another comment type for blog entries that has only a generic comment body field.
