G'day Jay,
I'm still kicking myself for not finding this big word.
When i viewed the solution, my initial reaction was well no wonder i could not find it because i have never heard of it & no idea what it means but when i clicked on the definition, it suddenly came rushing back to me that i had indeed encountered this word somewhere before & that was of course when playing this incredible game of chihuahua.
The excuse is that since i have had a little break from chi then i was entitled to forget. the word.
But Jay, my point is that this is what chi is all about, learning new words, expanding your vocabulary & even having a bit of fun by finding benchmark players that you can challenge on the scoreboard.
Anyway i am quite sure that neither of us will ever miss ampersand the next time that it pops up in a puzzle.
