Dear Professor X in French How can I translate "Dear Professor (His surname)" into French? More details: - This professor teaches at university level - I do not know him personally, but I am taking his class - He addressed me as "Chère (my name + surname)" Can I use "Cher Professeur (His surname)" in a formal email? Would that be adequate? If so, should I write "Professeur" or "professeur"?
