A translator is a person who helps translate documents from one language to another. They may be hired by businesses or governments, and they are typically responsible for translating written materials as well as spoken ones. A translator's job can often involve spending time in both countries where the languages being translated exist, so it is important that they have excellent communication skills. Additionally, translators must be able to understand complex grammar rules and idioms, which means that many of them also have degrees in linguistics or translation studies.
