Hence a diminutive of opson, opsarion (ὀψάριον), provides the modern Greek word for fish: psari (ψάρι).
The central focus of Greek personal morality on sophrosyne (approximately, moderation and temperate self-control) made opsophagia a matter of concern for moralists and satirists in the classical period.
[2] The term opsophagos, literally 'opson-eater', is used by classical authors to refer to people who, almost always, are fanatical about seafood, e.g. Philoxenus of Leucas.
Plato, probably mistakenly, derived the word opson from the verb ἕψω ― 'to boil'.
The term parásītos (πᾰράσῑτος) is also the root of the English word parasite.
