Inside Macintosh: AppleScript Language Guide / Part 2 - AppleScript Language Reference

Chapter 6 - Expressions

An expression is any series of AppleScript words that has a value. You use expressions to represent or derive values in scripts. When AppleScript encounters an expression, it converts it into an equivalent value. This is
known as evaluation.

Chapter 3 describes and gives examples of the simplest kinds of expressions, called literal expressions, which are representations of values in scripts. This chapter begins by describing how to evaluate expressions. It then describes five additional types of expressions:
