Translation is the interpreting of the meaning of a text and the subsequent production of an equivalent text, likewise called a "translation," that communicates the same message in another language. The text to be translated is called the "source text," and the language that it is to be translated into is called the "target language"; the final product is sometimes called target text Translation must take into account constraints that include context, the rules of grammar of the two languages, their writing conventions, and their idioms. A common misconception is that there exists a simple word-for-word correspondence between any two languages, and that translation is a straightforward mechanical process. A word-for-word translation, however, does not take into account context, grammar, conventions, and idioms.
