hello

expr =
  Map[
   ToString,
   {{t, h, i, s}, {i, s}, {a}, {t, e, s, t}, {m, e, s, s, a, g, e}},
   {2}];

=============

How could I go from:
{h,e,l,l,o}
to
{hello}?

That is the first step of what I am really looking to do. Which is 
to go from:
{{t,h,i,s},{i,s},{a},{t,e,s,t},{m,e,s,s,a,g,e}}
to
"this is a test message"

Thanks all,
Jason Ebaugh
