[Meaning something] good-for-nothing. But properly [it is] the petal of the poppy, and that of the anemone. [sc. The name comes] from plata/ssein ["to clap"], that is to make a sound. But by extension [it means] anything which has breadth. From this also [comes] platagh/ ["rattle"].[1] They used to infer from this the affection of those they loved, putting it on the opposite hand and the forefinger and striking against [it]. And if it made a sound, they were regarded with affection,[2] but if not, the opposite.
