Translation:Carrie is a fast American translator.
Since there could be confusion, you would use more words to insure there is no mistaking what you mean. You could say "Carrie is an English translator who translates Arabic into English", or "Carrie, who is from England, translates foreign languages into English", or "Carrie, who is English, translates English into Arabic", etc.
These questions are kind of silly. What is an american translator? They speak english in the USA.
Other questions said "Tunisian" or "Syrian" translator - but they all soeak arabic. Yeah they have their own dialects but they are all arabic translators.
Pleaee give us questions with substance.
??? An American translator is an American who can translate back and forth between two or more languages; say from English to Arabic and Arabic to English. A Tunisian translator is a Tunisian who can translate from two or more languages; say Arabic to French and English, French and English to Arabic, English to French....
When you go to a foreign country where you don't speak the language, one of the first things you're going to need is someone who can translate for you.
