Hi,

In your sentence at all means in any way.

Dear teacher,

Please explain more in every detail. What does “in any way” mean?

In my dictionary, people also say “in any way” but I don’t understand what it means.

Thanks

Hi,

In any way/in the slightest/in the least bit/in the smallest way and so on.

Dear Sir,

Please read: Is your father any better in any way?

So, the author liked to know if the father of sb was any better, even in any way?

Is it right?

I think the idea “in any way” has expressed in the word “any”. That means “any” = “in any way”. (in this case)

So, do you think one of these 2 words (“any” and “in any way” is redundant(unnecessary) because they refer the same idea. If not, how to distinguish clearly the meaning btw “any” and “in any way”?)

PS: Please write to me your explanation about the meaning of the sentence, including the best way to distinguis the meaning of “any” and the meaning of “in any way”

Again I have to say, please read my explanation.
