Interpretation, or interpreting, is an activity that consists of establishing, either simultaneously or consecutively, oral or gestural communications between two or more speakers who are not speaking (or signing) the same language.
The purpose of interpretation would normally be to increase the possibility of understanding, but sometimes, as in propaganda or brainwashing, the purpose may be to evade understanding and increase confusion.

In the Interpreter DVD, escalating events begin when U.N. translator Silvia Broome (Nicole Kidman) alleges that she has overheard a death threat against an African head of state, spoken in a rare dialect few people other than Silvia can understand.
With the words "The Teacher will never leave this room alive," in an instant, Silvia's life is turned upside down as she becomes a hunted target of the killers.
Now, as the danger of a major assassination on U.S. soil grows and Silvia's life hangs in the balance, Silvia and Tobin play out a gripping dance of evasion and revelation that keeps them both guessing as they race to stop a terrifying international crisis before it's too late.
Interpreting code is slower than running the compiled code because the interpreter must analyse each statement in the program each time it is executed and then perform the desired action whereas the compiled code just performs the action.
An interpreter might well use the same lexical analyzer and parser as the compiler and then interpret the resulting abstract syntax tree.
The IBM 550 Numeric Interpreter and IBM 557 Alphabetic Interpreter are typical examples from 1930 and 1954, respectively.
