Think about it this way.<p>Case 1: SRC-&gt;TGT (fluent) gives you a grammatically correct text that may have bits that are lost in translation. Misunderstood idioms and connotations. A reduction in nuance.<p>Case 2: (fluent) SRC-&gt;TGT gives you an incorrect text that contains errors of syntax and semantics, that doesn&#x27;t use natural sentence construction. It&#x27;ll reads like it was written by someone with less than a perfect grasp on the language, which will be true. They won&#x27;t be able to accurately convey the meaning because they won&#x27;t have an accurate grasp of the target language.<p>Also in case 1 you can consult expert quality reference texts to make up for your lack of knowledge in the source language. Not so in case 2.
