No, V7 used a hashed dictionary format; BSD uses the V7 version, and the
S5 version is similar.  V7 and BSD built it from "/usr/dict/words" (and
some other stuff, like the American/British lists).

Some release of S5 (or maybe some release prior to it) also eliminated
"/usr/dict/words", perhaps for the reason you stated.
