Very much so! Thanks for the great explanation!

I ended up with the following function:
zap_word() {
# Arguments: "word to delete" "word list to delete from"
echo $2 | sed "s/^/ / ; s/$/ / ; s/ $1 / / ; s/^ // ; s/ $//"
}
In this case, double quotes are needed because of the $1 usage. I was
delighted when Matthew suggested the double quotes, as that got it working
for me. Even better though, is now I understand *why*. :)
Thanks again!
