Quintilian, 8.3 (55)

“There is also that phenomenon which is called periergia—as I might call it, an ultimately useless carefulness in which a dilettante contrasts with a scholar the same way superstition differs from religion. So, to summarize, a word which helps neither the understanding nor the form can be said to be a mistake.”

Est etiam quae periergia vocatur, supervacua, ut sic dixerim, operositas, ut a diligenti curiosus et religione superstitio distat. Atque, ut semel finiam, verbum omne quod neque intellectum adiuvat neque ornatum vitiosum dici potest.
