Your edit to one of my posts
I am sorry,
I certainly did not mean to interfere with your style. What I read, when I read it, was a common typing error (in my perception) and I "corrected" it despite the fact that I usually to not "correct" personal statements of others.
Of course "What say you?" can be said in some English speaking communities. As an utterance or a direct quotation of one, it had triggered my inner automatism saying: "you must not write that" but I likely had not altered it. Please accept my apology. I learned writing English in a conservative British dominated environment when I was young. I am over 60 now. Teachers told us that we MUST write questions using "to do" always, absolutely no matter how they are uttered. We learned that, even in a word protocol of a speech, we have to write utterances like "What say you?" as "What do you say?", and we were allowed to loudly re-read it as "What say you?" if we knew positively from listening that it had been said so. As a language scientist, that I became meanwhile, I am far from supporting what we were taught, but it occasionaly bleeds through. Sorry again.
