I don’t mean to make this a Thread Game. Maybe someone can answer with a dictionary search or something.
The NY Times Spelling Bee has seven letters, which can be used multiple times, to form words. A word that uses all seven letters is called a “pangram”. A perfect pangram uses the letters exactly once, but I’m not looking for that.
The Spelling Bee never has an S in it, and the list of answers is limited to relatively common words.
Some words it allows are quite obscure to me and some words that I think are common, like “prion”, are not allowed. Be that as it may, I’m looking for the longest, relatively common, word that has exactly seven different letters in it and does not contain an S.
Mods: I’ll self-report this in case it really does belong in Thread Games.
/usr/dict/words has four 15-letter words without any S’s that use seven different letters:
inconveniencing
interconnection
nationalization
nonintervention
If you limit it to six different letters, the longest word is inconvenience
Well, they’re very rare in our Universe, because they tend to quickly encounter ordinary words and annihilate with them, leaving nothing but a high-energy spray of letters and phonemes.
