What does "target language" mean in the context of localization?

In the context of localization, the term "target language" refers specifically to the language into which content is translated. This is the language that audiences in a specific locale will read or interact with after localization efforts are completed. Localization involves not just translation but adapting various elements of the content to meet the cultural, linguistic, and contextual needs of the target audience, which emphasizes the importance of accurately identifying the target language.

The concept of target language is crucial for ensuring that the translated content appropriately conveys the intended message and resonates with the local audience. In contrast, the primary language of the content creator refers to the original language in which the content was produced, which plays a role in the translation process but is not what is referred to as "target language." The most commonly spoken language globally does not relate to specific localization efforts as it lacks context for tailored communication. Additionally, while the client's language might influence how the content is approached, it does not determine the target language for the translated content. Therefore, correctly understanding that the target language is the end medium for the localized content allows for effective communication in different regions.
