Jason Ebaugh: You can try the following: In[16]:= phrase = {{"t","h","i","s"},{"i","s"},{"a"},{"t","e","s","t"},{"m","e","s","s","a","g","e"}} Out[16]= {{t,h,i,s},{i,s},{a},{t,e,s,t},{m,e,s,s,a,g,e}} In[17]:= StringJoin[Flatten[Riffle[phrase," "],Infinity]] Out[17]= this is a test message However, I am concerned about how will you arrive at {h,e,l,l,o} or even {{t,h,i,s},{i,s},{a},{t,e,s,t},{m,e,s,s,a,g,e}}. You are asking us to help solve this particular case/problem. But depending on how you arrived at this list in may be possible to avoid the trap alltogether.
