In ordinary Greek: a STAGE ACTOR — the masked professional (the theater at Sepphoris stood an hour's walk from Nazareth). The Sermon's word for piety performed to an audience (Matthew 6:2, 5, 16), beside a matching verb in 6:1: righteousness done 'to be GAZED AT' (theathēnai — the root of 'theater'). English 'hypocrite' is this word, worn smooth. → first discussed at Matt 6:2
