matricide
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 > Greek (Woodhouse)

one who kills his mother: P. and V. μητραλοίας, ὁ, μητροκτόνος, ὁ (Plato but rare P.), V. μητροφόντης, ὁ.
