Redouble, double, or double again?
I have seen double and double again a lot. Redouble, not so much.
I found out that redouble can mean to double again, to double, or in general to intensify whether that is double, triple, quintuple, or something else.
So if I want to use double again I pretty much know when to use it. However I wouldn't know when to use redouble or if I should use it at all.
If I use redouble where I would usually use double then the reader would think that it has doubled twice.
If I use redouble where I would usually use triple or quintuple or something besides double then again the reader will think that it has doubled again when it might have tripled.
If I use redouble where I would usually use double again the reader wouldn't have the intensify vs double again confusion but still the reader might think "It is irrelavant to use redouble when you could just use double again."
So should I use redouble in any scenario when writing or editing or should I just use double, double again, triple etc. which I would usually use?
I am trying to expand my vocabulary while editing so that is why I am asking if I should ever use redouble?

"Redouble" is almost always used in the idiom to redouble one's effort, meaning to increase the effort one is exerting.
"Double again" has the very specific meaning of This was increased by 100% of the original, to make 200%, and will now be increased by 100% of that, making it 400% of the original.
Which one you want to use is dependent on context and your intended meaning.
