}

    cs = control sequence


Or you can leave some braces and one of the \expandafter commands
  (as in Frank's posting):

\newcommand{\mynewcommand}[2]{%
     \expandafter\newcommand\csname#1\endcsname{#2}%
}


This also works when #1 contains non-letter charcters;
e.g., digits and punctuation.

But in that case, to call the macro that was defined this
way, you need to use, e.g.  \csname item37name\endcsname
