     <h1>Lexical Environments</h1>
     <p>A <dfn>Lexical Environment</dfn> is a specification type used to define the association of |Identifier|s to specific variables and functions based upon the lexical nesting structure of ECMAScript code. A Lexical Environment consists of an Environment Record and a possibly null reference to an <em>outer</em> Lexical Environment. Usually a Lexical Environment is associated with some specific syntactic structure of ECMAScript code such as a |FunctionDeclaration|, a |BlockStatement|, or a |Catch| clause of a |TryStatement| and a new Lexical Environment is created each time such code is evaluated.</p>
-    <p>An Environment Record records the identifier bindings that are created within the scope of its associated Lexical Environment. It is referred to as the Lexical Environment's <dfn>EnvironmentRecord</dfn></p>

     <p>The outer environment reference is used to model the logical nesting of Lexical Environment values. The outer reference of a (inner) Lexical Environment is a reference to the Lexical Environment that logically surrounds the inner Lexical Environment. An outer Lexical Environment may, of course, have its own outer Lexical Environment. A Lexical Environment may serve as the outer environment for multiple inner Lexical Environments. For example, if a |FunctionDeclaration| contains two nested |FunctionDeclaration|s then the Lexical Environments of each of the nested functions will have as their outer Lexical Environment the Lexical Environment of the current evaluation of the surrounding function.</p>
     <p>A <dfn id="global-environment">global environment</dfn> is a Lexical Environment which does not have an outer environment. The global environment's outer environment reference is *null*. A global environment's EnvironmentRecord may be prepopulated with identifier bindings and includes an associated global object whose properties provide some of the global environment's identifier bindings. As ECMAScript code is executed, additional properties may be added to the global object and the initial properties may be modified.</p>
     <p>A <dfn id="module-environment">module environment</dfn> is a Lexical Environment that contains the bindings for the top level declarations of a |Module|. It also contains the bindings that are explicitly imported by the |Module|. The outer environment of a module environment is a global environment.</p>
