Is そんなに short for そのように？


As specified in the title, is そんなに just short for そのように？ Likewise for こんなに and
あんなに。




No, そんなに is not the abbreviation of そのように. It is そんな, an adjective, appended
with に to make it an adverb. It means "so much; so".

そのように is その appended to the noun 様 (which is the manner in which something is
done) and then turned into an adverb with に. It means what you would expect it
to mean: "In that way/manner". They are not interchangeable. Here are some
examples:

> そのようにしてください。〇  
>  そんなにしてください。☓  
>  Please do it in that way.

> そんなに怒らないでください。= Please don't get that mad.  
>  そのように怒らないでください。= Please don't get mad in that manner.  
>
