This paper discusses the use of the word γλίσχρος (‘sticky’), which Platonists use to disqualify certain, mostly Stoic, etymologies. I argue that the expression derives from Plato Crat. 435c, a passage in which Socrates sets out a theory of word formation that informs Stoic etymologies. I furthermore suggest that when Neoplatonists use γλίσχρος to reject certain interpretations of Plato’s texts as misguided, this is because these interpretations are reminiscent of Stoic exegetical practices.
