There is a common misconception that translation and interpretation are the same line of work.
Translators work with texts while interpreters orally navigate between two parties.
Translators work in agencies or independently as freelancers.
Interpreters often work in hospitals or courtrooms.
Both work with source, or original, languages and target, or destination languages.
Both prefixes, trans- and inter- mean between.
Fluency in more than one language is required for both professions.
