ὕπαφρος
ἄλογον δὴ τὸ μήτε μάχης ἄρξασθαι μήτε τοὺς φίλους φυλάξαι, ἐὰν ὑπό γε τῶν βαρβάρων ἀδικῆσθε → It is irrational neither to begin battle nor to guard the friends, if you are ever wronged by the foreigners
English (LSJ)
ον,
A frothy, πέλαγος Sch.BT Il.14.16; πτύσματα Gal.9.564. II = κρυφαῖος, Heraclid. Tarent. ap. Erot., who cites Hp.de Arte10, S.Frr.236,312; so ὕπαφρον ὄμμ' ἔχων (of Odysseus) in E.Rh.711 (lyr.), acc. to Sch.; Hsch. explains by τὸ μὴ φανερόν, also κρύφιον καὶ ὕπουλον, and τὸ ὑγρασίαν ἔχον ἐμφερῆ ἀφρῷ (i.e. blear-eyed in E. l.c.). [ὕπαφρον codd. Hp., E., Hsch., Phot.; ὕποφρος (-ον) codd.Erot.; in Hp. this sense hardly fits, and Littré accepts Schneider's cj. ὑπόφορον 'pierced with ducts'.]
Greek (Liddell-Scott)
