Hello. I would like to clarify one doubt of mine regarding the use of the word professor in English. In romance language like Spanish, French, Italian, Catalan, Portuguese, etc. a person is addressed professor if he teaches in college or university level. This doesn't take into consideration the number of years of experience, post-graduate studies, authorship or marked competence in the field he practices in. I've had always this impression that the title of professor in English is reserved to those with highly specialized training and experience in the subjects of his field. In fact, there are professorial chairs that are being created. My question is, is any person teaching at the university level automatically called professor? Please enlighten me. Thanks.
