I am flattered over all this assistance.
Thank you indeed Parv, and also Will Maier, you guys have surely
taught me a lot.
I got my hands full of work currently, but I'll test this script
ASAP, and get back to you all.
This is going to be great! Here is my copy and paste of it.

echo "Combining $1 with $2 to $3."
[ -f "$save" ] && mv -f "$save" "$save--OLD"
{ while read word_1; do
while read word_2; do
printf "%s%s\n%s%s\n" "$word_1" "$word_2" "$word_2" "$word_1"
done < "$2"
done < "$1" } | sort -u >> "$3"

Does it look alright so far?
Thanks again,
Vaaf
