It all began with a party -- one that I did not attend. The next day, someone mentioned to me that word games had been played at the party, and that a word with the pattern 1231231 (where different letters are represented by different digits) had been sought. I replied (immediately, so I like to think) with alfalfa and entente, and later with the German words Kuckuck ('cuckoo') and endende ('ending', as a weak adjective).
