I had always heard that "strengths" was the longest one-syllable word in English, with 9 syllables. The other day, I noticed that "straights" also has 9 letters. I wasn't sure if that was a word, but if "gays" is, and if "marrieds" is (I hate that word, definitely a pet peeve of mine), then "straights" should be. A quick google search confirmed that "straights" is indeed a word in semi-popular use, but it also turned up a whole bunch of other one-syllable, 9-letter words, and of course Wikipedia takes the cake with the most comprehensive discussion of the topic, replete with some possible 10- and 11-letterers. Who knew? Also, random question: what are your favorite bits of English word trivia? Or am I the only nerd in that regard?
p.s. I love the Wikipedia "list" articles. They just make me laugh.
