Among the words that I resent being not being admitted to the Scrabble dictionary are older, but still extant, second and third person forms of verbs: as in, e.g. Biblical style 'thou sayest', 'he goeth', &c. I contend that these must theoretically exist, & should ∴ be admissible, even for more recently coined verbs, so that I should expect an opponent to accept 'phonest', 'texteth'...
