When fluency is achieved through the standard or most widely used form of the translating language, the illusion that the translation is not a translation but the source text is produced, and the inevitable assimilation of that text to values in the receiving culture is concealed. Venuti sees two main methods of questioning or forestalling these domesticating effects: one is to choose source texts that run counter to existing patterns of translating from particular languages and cultures, challenging canons in the receiving culture; the other is to vary the standard dialect, to experiment with nonstandard linguistic items (regional and social dialects, colloquialism and slang, obscenity, archaism, neologism), although not arbitrarily, taking into account the features of the source text. These methods do not give back the source text unmediated; they are foreignizing, constructing a sense of the foreign that is always already mediated by receiving cultural values.
