  • Byzantine
  • n.

    A native or inhabitant of Byzantium, now Constantinople; sometimes, applied to an inhabitant of the modern city of Constantinople. C () C is the third letter of the English alphabet.

In Anglo-Saxon words, or Old English before the Norman Conquest, it always has the sound of k. The Latin C was the same letter as the Greek /, /, and came from the Greek alphabet.
