Professer or Professor: How Do You Spell Professor?

English is a messy language filled with special cases and exceptions. You may even run into this very issue when you use professer or professor in text. Don’t fret! This spelling guide breaks the differences and includes tips and examples!

Professor Meaning: What Is It?

Professor has two definitions. It can be:

  1. A person who professes, avows or declares.
  2. Someone in academia whom has studied a subject long enough to pursue teaching classes on that subject.

We usually associate the word “professor” with the second definition. How about the first professor meaning? Well, it dates back to the 1400s. It was used in reference to a person’s declaration of belief in God and is how “professer” is valid in French. The academic meaning is derived from the Latin for “a person who professes high-level expertise in some subject.”

Using Professor in a Sentence

You might use or hear the word “professor” in everyday conversations, but how often do you see it in writing? Probably not enough! So, we’ve prepared five examples using the word “professor.”


  • “Man, you are so lucky that Professor MacDougal is teaching your chemistry class! His lectures are never boring; it’s always fun and interesting!”
  • “What is a professor but a woman who focused on books learning at the expense of socialization in order to then make a living off of all that learning?”
  • “Professor Spelling is no doubt tired of jokes being made at his expense due to having that name and being in the English department.”
  • “Professor Meaning is a new app that helps students better remember the spelling and etymology of various words.”
  • “If I had one piece of advice to give to you when going to college, it would be that professors are accountable for what they are teaching you because you are directly paying them for their knowledge and expertise.”

Professer or Professor: How to Spell Professor?

Unless you are taking some sort of test in French, you only need to keep one spelling in mind and that correct spelling, in English, is “professor.”

A professor is like several other professions. It involves an act and ends in an “-or;” confessors draw out confessions, councilors sit on some sort of council, editors edit content, and so on.

There is only one E in the word professor, not two; and while most people rarely forget this element, the word always has two Ss.

It is also worth mentioning that, as a title, the P in professor should always be capitalized when preceding a specific name (Professor James Emile Lawry) or brand of study (Professor of Anthropology).

Trick to Remembering the Spelling

The most basic way of remembering the proper spelling is to keep in mind its Latin roots. You should also note how other professions like editor and counselor have “-or” at the end. Since a professor professes, meaning he knows enough to get paid for his knowledge on the topic, you wind up with “profess” plus “-or,” resulting in “professor.”

In Summary

Professor is one of those words that can confuse you. Should it be professer or professor? As this article has shown, one of the best ways of keeping the difference in mind is that a professor is a profession and very few professions end in “-er.” The various tips and examples provided above should have you feeling perfectly competent at spelling this word correctly.
