Frequently Asked Questions about Principle Collocations
What is the difference between “in principle” and “on principle”?
“In principle” means that you agree with the general idea or theory (e.g., “In principle, the idea is good”). “On principle” means you are doing something because of your personal moral beliefs (e.g., “I refused the gift on principle”).
Can “principle” be used as a verb?
No, in modern English, “principle” is strictly a noun. If you want to describe someone who has strong principles, you should use the adjective “principled” (e.g., “She is a very principled leader”).
Is it “adhere to” or “adhere with” principles?
The correct collocation is always adhere to. Using “adhere with” is a common error for ESL learners.
