Why does Lisp use prefix notation?
Prefix notation has seen wide application in Lisp S-expressions, where the brackets are required since the operators in the language are themselves data (first-class functions). Lisp functions may also be variadic. The Tcl programming language, much like Lisp also uses Polish notation through the mathop library.

How do you read the prefix notation?
Prefix notation puts the operator before all of the operands. This means that the precedence is always clear.

How are prefix expressions used in Common Lisp?
Notice that LISP languages (e.g. Common Lisp, Scheme, Clojure and many specific dialects inspired by them like AutoLISP, Emacs-LISP, MELT, etc…) are all using a prefix-syntax: every expression starts with a left parenthesis, then the operator, then the operands, then the right parenthesis. These expressions are called S-expressions.
