ἐκκιρρόω
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)
pf. ἐκκεκίρρωκα, become hardened, Hippiatr.104.
Spanish (DGE)
endurecer οἱ (ἵπποι) ... ἐκκεκιρρωκότες τὰ κατ' ὄνυχα τῆς ὁπλῆς Hippiatr.104.2.2.
