8-Letter Words Starting With O

Last updated: October 1, 2026

Counting only the ENABLE word list, 972 entries are 8-letter words that start with O. That is about 0.56% of the list. All of them have the same length, so they differ only in their letters. Using commonly used tile values, OXAZEPAM (28 points) scores the most. 236 of them use no letter twice, which matters in games where every tile is separate. Games use their own dictionaries, so a word here isn't automatically playable everywhere.
