Have a look at functions in StrUtils like:

function WordCount(const S: string; const WordDelims: TSysCharSet): Integer;
function WordPosition(const N: Integer; const S: string; const 
WordDelims: TSysCharSet): Integer;
function ExtractWord(N: Integer; const S: string;  const WordDelims: 
TSysCharSet): string;inline;
function ExtractWordPos(N: Integer; const S: string; const WordDelims: 
TSysCharSet; var Pos: Integer): string;
