Occasionally somebody sends me a suggestion via email. But I think this is the first time I've received a suggestion resulting from a Chihuahua puzzle book.
My correspondent had been playing puzzle 2 in the 7-by-many puzzles book, Volume 3, and was unhappy that
metropole wasn't listed in the solutions. I don't think I was aware of this word, other than as a hotel name. But it is listed, in lower case, in a number of dictionaries, including the online Oxford and Merriam-Webster and Wiktionary. It has a few meanings, but the main ones seem to be the parent state of a colony, or the main town of a territory.
A recent usage example is from the
Washington Examiner of 6 May:
...her thesis that the “erasure of empire” is rooted in a “fundamental incompatibility between the imperial project and British institutions developed in the metropole” is necessarily more speculative.
I've added
metropole as a rare word. The letters for this word may not yet have come up in a daily puzzle, but they probably will some time.
