A. rise of the sea, as at flood-tide, πλημυρὶς ἐκ πόντοιο of the wave caused by the rock thrown by the Cyclops, Od. 9.486; flood-tide, opp. ἄμπωτις (ebb), π. τῆς θαλάσσης μεγάλη Hdt. 8.129; π. πόντου B. Fr. 30; ἡ ἔξω π. Arist. Mete. 366a20, cf. Str. 3.3.7 (pl.), S.E. M. 9.79 (pl.).
2. generally, flood, deluge, Arist. Mu. 397a28 (pl.); of tears, σταγόνες . . δυσχίμου πλημυρίδος A. Ch. 186; ὀφθαλμοτέγκτῳ δεύεται πλημυρίδι E. Alc. 184.
3. redundance, congestion of the fluids of the body, Hp. Acut. 62. [υ Hom. l.c., and prob. in B.l.c.; υ Trag., but υ in later Ep., cf. A.R. 4.1269, 1241: in πλήμυρα, πλημυρέω, πλημύρω, υ always.] (The spelling πλημμ‐ in this word and its cognates commonly found in codd. arises from the false etymology from πλήν, μύρομαι; the correct spelling is found in B. 5.107, POxy. 1409.17, OGI 666.8 (v. πλημύρω), etc., and good Mss. of Hp. Acut. 62, AP 5.203 (Mel.), cf. Archil. 97.)
