There are things that are seemingly OK but have problems within. For instance a food might seem OK but be poisonous. Or a translation might seem OK but in fact be awful since it has omitted or changed the main message. How can we describe such things? Even people might be seemingly nice but internally wicked!
I am particularly interested for words/phrases/idioms that describe the above-mentioned like translations.
This translations is the word I am looking for, it seems OK but actually says something completely different to what the original sentence says!
I am interested especially in a word with a formal register, which is suitable to be written in an academic text. Is outwardly good/flawless a good fit?
