[1] The primary headword klhdw/n has the same or similar glossed in other lexica; references at Photius kappa775 Theodoridis. See also (e.g.) omicron 321, omicron 322, omicron 615, omicron 726, omicron 730, under delta 1364, and generally Donald Lateiner, "Signifying names and other ominous accidental utterances in classical historiography", Greek, Roman & Byzantine Studies 45 (2005) 35-57.
[2] cf. George the Monk, Chronicon 237.14, glossing the singular of the noun with this phrase. Presumably, therefore, the plural comes from somewhere else; perhaps Isaiah 2.6 LXX. See anyway under pi 465.
