Dear des, Welcome aBoard.
I found ambigu while checking spelling of another word. I was using the Oxford English. I was having some fun with my post and, at same time, considering using "ambigu" on my next invitation to friends and thereby have an opening conversation and a few laughs built in to each arrival at the party since many of my chums are "wordies."
Hang around, des, you'll find I do love to shake the beehive every now and then to get everyone buzzing.
Aloha to you, dear newbie!
