In analytic philosophy and computer science, referential transparency and referential opacity are properties of linguistic constructions, [a] and by extension of languages. A linguistic construction is called referentially transparent when for any expression built from it, replacing a subexpression with another one that denotes the same value [b] does not change the value of the expression.
The term is used in philosophical theories of reference, and is to be contrasted with referentially transparent context.In rough outline: Opacity: "Mary believes that Cicero is a great orator" gives rise to an opaque context; although Cicero was also called 'Tully', [2] we can't simply substitute 'Tully' for 'Cicero' in this context ("Mary believes that Tully is a great orator") and guarantee ...
The six factors of an effective verbal communication. To each one corresponds a communication function (not displayed in this picture). [1] Roman Jakobson defined six functions of language (or communication functions), according to which an effective act of verbal communication can be described. [2] Each of the functions has an associated factor.
Word and Object is a 1960 work by the philosopher Willard Van Orman Quine, in which the author expands upon the line of thought of his earlier writings in From a Logical Point of View (1953), and reformulates some of his earlier arguments, such as his attack in "Two Dogmas of Empiricism" on the analytic–synthetic distinction.

Normatively, the phrase may describe the effort to suit one's rhetoric to the widest possible audience, without losing relevant information in the process. Advocates of normative linguistic transparency often argue that linguistic opacity is dangerous to a democracy.
Referential transparency means that an expression (such as a function call) can be replaced with its value. This requires that the expression is pure , that is to say the expression must be deterministic (always give the same value for the same input) and side-effect free.
Conversation is defined as what is happening behaviorally between two or more participants in the communication process. Conversation is the exchange or interaction itself. [2] The process of the text and conversation exchange is reciprocal: text needs conversation and vice versa for the process of communication to occur. Text, or content, must ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
