Translation is written communication. Translators specialize in 2 languages and change texts that are written in one language into another language. They do not change the content, tone or style of the message.
Translation is a challenging task that requires a strong knowledge of languages, good writing skills and, often, knowledge of a specific subject.
Not everyone who speaks 2 languages is a good translator. It is recommended that you use the services of a professional translator. Translators are specifically trained to make sure:
• The language they use is accurate and consistent.
• They have a thorough knowledge of the vocabulary in a particular field of expertise.
• They maintain the content, context and style of the original material to the greatest extent possible.
