Lexical scope

Meaning in software engineering, with examples

nounCommon term

In software engineering, lexical scope means: A rule that resolves names from the surrounding code structure, rather than from the sequence of function calls.

In Turkish: sözcüksel kapsam

How it is used

Use it when explaining which variable a nested function can access. Contrast it with scope determined by callers.

Example sentences

  1. Because of lexical scope, the callback reads the outer function's limit.

    The variable comes from where the callback was defined, even if another function runs it.

  2. The reviewer used lexical scope to explain why the caller's count was ignored.

    A matching name in the caller does not automatically replace the binding visible at definition.

Common collocations

  • lexical scope rules
  • lexical scope resolution
  • closureA function together with access to variables from its surrounding lexical environment, even when it is called from elsewhere.
  • variableA name in a program that stores a value, such as a number, text or list, so that the code can use or change that value later.
