The etymological method displayed at considerable length in the Cratylus is widely assumed to be intended by Plato as an object of ridicule. In my 2003 monograph Plato’s Cratylus I resisted this assumption. In the present paper I seek to strengthen my case by arguing that in Plato’s major work on philosophical logic, the Sophist, the same method is re-employed twice, at 221 a–c and 228 b–e, for entirely serious purposes.
