Hi, guys,
I was helping a colleague to check an official letter in English, and came across an interesting phrase - "in according to". I wanted to change it into either "in accordance with" or "according to", but the colleague told me that the phrase had been suggested to him by another colleague of ours. I'd think that this second colleague was mistaken, but the problem is that she's a proficient English speaker (has a linguistics education).
So, the question is whether "in according to" is a super-official usage I'm not aware of, or the one who suggested this phrase was mistaken.
Since I've touched this question, could you please also tell me which one sounds more official: "in accordance with" or "according to" (or "in according to", if it's correct)?
