What does the word Christ mean in Greek?

The word "Christ" is actually a transliteration of the Greek word Χριστός (Christos). It means "anointed one" or "the Messiah."

In ancient Jewish tradition, the word "Messiah" (Hebrew: מָשִׁיחַ, Mashiach) referred to a divinely appointed leader who would usher in a time of peace and prosperity.

The Greek word "Christos" was adopted by early Christians to refer to Jesus of Nazareth as the fulfillment of the messianic prophecies.
