Examples:

• He was unfazed by the difficult questions.

The Origin of Unphased or Unfazed

The word unfazed comes from faze, a verb meaning to disturb, unsettle, or bother someone. Adding the prefix un- gives it the opposite meaning: not disturbed or bothered.

The word unphased comes from phase, which refers to a stage or period in a process. Adding un- suggests that something is not divided into phases.

Although the words look and sound similar, they come from different base words. Remembering the difference between faze and phase makes the spelling easier to understand.
