[Meaning a] forger; also a ne'er-do-well plain and simple. Also [sc. attested is the related noun] 'easy-operating', [meaning] an insouciance toward everything, and opportunism, and boldness. But Xenophon also used the word in reference to equanimity.[1]
But Polybius says concerning a treasonous household: "Why is it that we are unable to cease our foolishness though we are deceived in the same ways by the same people? For this type of easy-operating has already been practiced many times by many people. And while its occurrence among others is perhaps not surprising, it is surprising for it to occur to those among whom the source of this wrongdoing resides."[2]
And elsewhere: "injustice in private does not differ at all from the communal ones or those that happen in great number and on a large scale. In fact it is in private that the tribe of easy-operators and thieves is tripped up, most often in the following manner: by not acting justly toward one another and in general [through] their inconstancies toward one another."[3]
