'Did not even know' or ' even did not know'? Which of these tow is more acceptable or preferable? -------- He did not even know his daughter beforeher 11th birthday. -------- He even did not know his daughter before her 11th birthday. I've seen native English speakers write either of them. So I'm wondering: is there anything different between them-- if both are correct in grammar? which is better? Or, which is more suitable for a certain context? What's the specific context suitable for each one? Thank you!
