ἀπευφημισμός
From LSJ
Έγ', ὦ ταλαίπωρ', αὐτὸς ὧν χρείᾳ πάρει. Τὰ πολλὰ γάρ τοι ῥήματ' ἢ τέρψαντά τι, ἢ δυσχεράναντ', ἢ κατοικτίσαντά πως, παρέσχε φωνὴν τοῖς ἀφωνήτοις τινά –> Wretched brother, tell him what you need. A multitude of words can be pleasurable, burdensome, or they can arouse pity somehow — they give a kind of voice to the voiceless.
English (LSJ)
ὁ, -οῦ χάριν out of politeness, Phld.Lib.p.56O.
Spanish (DGE)
-οῦ, ὁ cortesía ἀπευφημισμοῦ χάριν Phld.Lib.p.56.
