O'Reilly publishes a book called "Mastering Regular Expressions". It
claims to be for people who have never used them before. Even so, while I
don't consider myself any better than the average bear, I also don't feel
I quite fall into the dummy category either. Nevertheless I find the
subject difficult.

Although Luke's solution also works, yours is simpler (after changing
flist
from "abcde bc de" to ". abcde bc de ." -- see my reply to Luke for
details).
And this begs the question -- how does one know when single quotes, double
quotes or no quotes are appropriate? Is there a "regexp for Dummies"
document out there (the man page is a bit thick)?

Any chance you can provide an example?
Thanks for your help!

Do
echo $flist | sed -e "s/ $fn / /"
Note the included delimiters on either side of the variable, and the
retention
of one delimiter in the substitution string.
You could also use 'awk'.
