翻訳 - ヒンディー語-ベトナム語 - Sorry-translation-expert

literally - "sorry this translation can only be carried out by experts."
in hindi, saying "this translation can only be carried out by AN expert" could have the implication that the translation could only be carried out by one particular expert, since the word for the indefinite article 'a', is the same as the word for 'one'.
