Scylla
Pronunciation : Scyl"la
Part of Speech : n.
Definition : Defn: A dangerous rock on the Italian coast opposite the whirpool Charybdis on the coast of Sicily, -- both personified in classical literature as ravenous monsters. The passage between them was formerly considered perilous; hence, the saying "Between Scylla and Charybdis," signifying a great peril on either hand.
