כהן
"כהן" (Kohen) means "priest" in Hebrew.
Here...'כהן' is used to describe a priest or clergyman in a religious setting, specifically within Judaism.
הכהן בבית הכנסת קורא את התורה בקול רם.
The priest in the synagogue reads the Torah aloud.
In this case, 'כהן' serves as a proper surname, likely of Jewish origin.

Professor Cohen gave an inspiring lecture on modern physics.
Here, 'כהן' is again a surname, used contextually as the family name of an individual who is likely well-known in the given scenario.
