"Thank you, professor" is a common way to express gratitude to a university teacher in Engpsh.

The origin of "professor" as a term of address for university teachers comes from the Latin word "professor," which means "person who professes" or "declares openly." The term was first used in Engpsh in the late 16th century to refer to university teachers, and it has since become a common way to refer to and address such individuals.

Examples:

"Thank you for taking the time to meet with me today, Professor Smith."
"Thank you for the fascinating lecture, Professor Jones. Your insights were truly enpghtening."

Chinese Translation:
