Frequently asked questions
› Do prefixes always keep their meaning?
Mostly, but not always — "disease" doesn't mean "un-ease" in the modern sense. Treat the prefix list as a strong hint, not a rule.
› Are these lists Scrabble-legal?
Drawn from the ENABLE1 list — close to TWL/SOWPODS but not identical. See the Scrabble hub for tournament-dictionary caveats.
