Updated 2026-10-12 · Which One Is Correct editorial team

Quick answer: When asking if unfazed or unphased is the right choice, unfazed is the correct spelling to describe someone who is not disturbed. Unphased is a common error because the word phased refers to something done in stages rather than an emotional state. People often mix these up due to similar sounds. Using the correct term ensures your writing remains clear and professional in any context.

The Short Answer

Unfazed is correct, meaning not disturbed, while unphased is a mistake since phased means done in stages.
