Long monosyllabic word

Trying to think of the longest word in the English language with one syllable. I can think of a few with nine letters, e.g., strengths. Is there a ten-letter word out there?

BTW, I had no recollection that I had such a frivolous first reply to that thread.

Thanks, I really should search before I type…
