Radical translation is a thought experiment in Word and Object, a major philosophical work from American philosopher Willard Van Orman Quine. It is used as an introduction to his theory of the indeterminacy of translation, and specifically to prove the point of inscrutability of reference. Using this concept of radical translation, Quine paints a setting where a linguist discovers a native linguistic community whose linguistic system is completely unrelated to any language familiar to the linguist. Quine then describes the steps taken by the linguist in his attempt to fully translate this unfamiliar language based on the only data he has; the events happening around him combined with the verbal and non-verbal behaviour of natives.
