13-Letter Words Starting With A

Last updated: October 1, 2026

Counting only the ENABLE word list, 520 entries are 13-letter words that start with A. That is about 0.30% of the list. All of them have the same length, so they differ only in their letters. By common tile values the top scorer is ACHROMATIZING (30 points); board bonuses aren't counted. 0 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.
