σύριχος
From LSJ
ὃν οὐ τύπτει λόγος οὐδὲ ῥάβδος → if words don't get through, neither a beating will | if the carrot doesn't work, the stick will not work either | whom words do not strike, neither does the rod

[Seite 1040] ὁ, = ὑῤῥίσκος, Alexis bei Ath. III, 76 d, zw.
Greek (Liddell-Scott)
σύρῐχος: ὁ, ἴδε ὑριχός.
