If you like to consider your list of arguments as a list of argument lists (of one argument here): In[8]:= aa = Partition[a,1] Out[8]= {{a1}, {a2}, {a3}} then In[9]:= MapThread[Apply,{f, aa}] Out[9]= {f1[a1], f2[a2], f3[a3]} else In[10]:= MapThread[#1@#2&,{f, a}] Out[10]= {f1[a1], f2[a2], f3[a3]} -- Hartmut Wolf
