OK, some people know how to \renewenvironment{paragraph}, but what is it 
good for?

I rather guess that wawan wants that each paragraph starts with some 
<start> end ends with some <end>, so he types

     Hello world!

and gets

     <start>Hello world!<end>

However, to achieve this by some \renewenvironment{paragraph} is sort of 
voodoo thinking. Rather (a sketch only)

     \everypar{<start>}
     \let\formerpar\par \def\par{<end>\formerpar}

This is just a sketch in particular because it is not very compatible with 
LaTeX's use of \everypar and \par. Sorry, I am in a hurry ...
