Abbreviate everything [released]

−0

Challenge

Make a program that takes input of a string and abbreviate it.

All letters of an abbreviation are capitalized, so keep that in mind.
Whitespace, numbers and non-English characters are ignored.
If the inputted string is a paragraph (2+ sentences), the abbreviation will be split by spaces ( ) where ., ? or ! are, while commas (,) are ignored in this splitting scenario.
Words that are connected by hyphens (-) will result to only one letter.
The only non-alphabetical characters to remain in the result are colons (:) and semicolons (;).
This is code-golf, so shortest program in each language wins.
