A meatless salad may be referred to as a salad-salad, as opposed to a tuna salad.. Contrastive focus reduplication, [1] also called contrastive reduplication, [1] identical constituent compounding, [2] [3] lexical cloning, [4] [5] or the double construction, is a type of syntactic reduplication found in some languages.
Lexical tokenization is the conversion of a raw text into (semantically or syntactically) meaningful lexical tokens, belonging to categories defined by a "lexer" program, such as identifiers, operators, grouping symbols, and data types. The resulting tokens are then passed on to some other form of processing.
Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories (nonterminal) and terminal symbols.

Strictly speaking [b] and in practice for most programming languages, "part of a program" refers to a portion of source code (area of text), and is known as lexical scope. In some languages, however, "part of a program" refers to a portion of run time (period during execution ), and is known as dynamic scope .
The process of actually making another exact replica of the object instead of just its reference is called cloning. In most languages, the language or libraries can facilitate some sort of cloning. In Java, the Object class contains the clone() method, which copies the object and returns a reference to that copied object.
The semantic gap characterizes the difference between two descriptions of an object by different linguistic representations, for instance languages or symbols. According to Andreas M. Hein, the semantic gap can be defined as "the difference in meaning between constructs formed within different representation systems". [1]
The term was first used in the semantic literature in 1988 by Marc Moens and Mark Steedman, who adopted it due to its "loose analogy with type-coercion in programming languages.” [3] In his written framework of the generative lexicon (a formal compositional approach to lexical semantics), Pustejovsky (1995:111) defines coercion as "a semantic ...
In the above UML class diagram, the Client class refers to the Prototype interface for cloning a Product. The Product1 class implements the Prototype interface by creating a copy of itself. The UML sequence diagram shows the run-time interactions: The Client object calls clone() on a prototype:Product1 object, which creates and returns a copy ...
