4. Type Specifiers

In Common Lisp, types are named by Lisp objects, specifically symbols and lists, called type specifiers. Symbols name predefined classes of objects, whereas lists usually indicate combinations or specializations of simpler types. Symbols or lists may also be abbreviations for types that could be specified in other ways.
