Most mornings move through a Spelling Bee style word hunt, a quick crossword, a few anagram rounds, and a Scrabble like rack in her head, words turning over while the coffee is still hot. And then there is Wordle, her favorite, the small five square heartbeat that sets the tone for the day. She notices what people can recall on the clock, where near spellings and double letters trigger doubt, and which everyday words still feel fair. Readers come for wins that feel earned: familiar vocabulary, steady difficulty, and none of the gotcha tricks that make a puzzle feel smug.
