1. Translation into two languages: This is the most common meaning. It refers to translating a text from one language to another, and then translating that translation into a third language.
Example: You have a document in Spanish that needs to be translated into English, and then the English translation needs to be translated into French.
2. Back translation: This involves translating a text from one language to another, and then translating the translation back into the original language. This is often used to check the accuracy of the first translation.
Example: You translate a document from English to Spanish, and then translate that Spanish translation back into English. Comparing the original English document with the back-translated version can help identify any errors or inconsistencies.
3. Iterative translation: This refers to a process where a text is translated multiple times, with each translation building upon the previous one. This can be used to ensure accuracy, clarity, and fluency in the final translation.
Example: A document is first translated from English to French, then reviewed by a native French speaker, who makes revisions and improvements. The revised French translation is then translated back into English for further review and refinement.
4. Double interpretation: This refers to a situation where two interpreters are involved, with one interpreting from the source language to the target language, and the other interpreting from the target language back to the source language. This is sometimes used in formal settings, such as diplomatic negotiations, to ensure accurate and complete communication.
Example: A diplomat speaks in French, and one interpreter translates to English. The English interpreter then translates the English back into French for the other diplomat.
To understand the specific meaning of "double translation" in a particular context, it's important to consider the surrounding information. For example, the use of the term "back translation" can help clarify that the translation is being used for quality control purposes.
