Principle Engineer

My email signature at work has my name, followed by the words, “Principle Engineer.” It’s been that way for probably two years.

An Indian engineer pointed out that it should be Principal, not Principle. He also pointed out that English is his fourth language.

I looked up both definitions just to be sure.

principle 
–noun 1. an accepted or professed rule of action or conduct: a person of good moral principles.

vs

principal
–adjective 1. first or highest in rank, importance, value, etc.; chief; foremost.

The more I think about it, the more I like it the way it is. 🙂
