  It's difficult to answer this question unless you say what utility you
intend to use the regular expression with.

  For example, with emacs (and possibly with ex and vi, I'm not sure), you can
use "\<" and "\>" to delimit a word in a regular expression.

  With "grep", you can use the "-w" argument to tell it to look for words only.

  With "perl", you can use "\b" to signify a word boundary.
