Anu's theme a couple of weeks ago was words with three consecutive letters in strict alphabetical order somewhere in them. tsuwm noted the pattern very early, and I'm sure others did too but didn't comment.

There are many such words. I suppose someone might take up the challenge of finding a representative word with each of the 24 possible combinations, though I suspect the obvious oddballs such as "-jkl-" or "-wxy-" may have no expansion in English. (If you are riding a bicycle in Agra and there is pedestrian in your way, I suppose you might activate your "Taj-klaxon," but that's a bit of a reach, don't you think? And hyphenated, too; that should be against the rules)

Query/speculation/challenge:
-Are there any four-letter-sequence words?
I finally came up with "understudy - are there others?
-How about a word with a five-letter sequence, or longer?
(Has all this been done before and I'm just reinventing the wheel?)
