Same entry in ps.-Zonaras; similar one, according to Adler, in the Ambrosian Lexicon.
The headword is aorist active infinitive of eu)ploe/w. It must be quoted somewhere -- perhaps the maxim preserved as Isocrates fr. 25: "to have a good voyage needs a [sc. good] steersman and wind, but to be happy needs [sc. good] reasoning and skill").
cf. epsilon 3654, nu 604.
