This is a nice easy one... you're bound to get lots of replies. It's not clear that you start off with characters (in Mathematica, that's strings of length one) - So I'll assume not. Here's my attempt at producing what you want (I've converted the outputs to Raw InputForm so that you can see the quote marks): In[1]:= test1={{t,h,i,s},{i,s},{a},{t,e,s,t},{m,e,s,s,a,g,e}} Out[1]={{t, h, i, s}, {i, s}, {a}, {t, e, s, t}, {m, e, s, s, a, g, e}} In[2]:= test2=Map[ToString,test1,{2}] Out[2]={{"t", "h", "i", "s"}, {"i", "s"}, {"a"}, {"t", "e", "s", "t"}, {"m", "e", "s", "s", "a", "g", "e"}} In[3]:= StringJoin[Riffle[test2," "]] Out[3]="this is a test message" Simon On Apr 3, 6:59 pm, eba... at illinois.edu wrote: > 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.
