What does “fazed” mean?
Fazed means disturbed, shaken or thrown off balance. It is the past tense of the verb faze, which usually appears in negative sentences: “Nothing fazes her,” or “He wasn’t fazed by the criticism.”
The related adjective unfazed means calm or unbothered. You will mostly see these words in sentences about staying cool under pressure.
Is “fazed” a real word?
Yes. Fazed is the past tense of faze, a standard English verb meaning to disturb or disconcert, and it appears in major dictionaries. Some people assume it is a misspelling of phased, but it is the correct word whenever you mean bothered or rattled.
What does “phased” mean?
Phased means done or introduced in stages. It is the past tense of the verb phase, which comes from the noun phase: a stage or period in a process, like a phase of the moon or a difficult phase in life.
The verb mostly appears in phrases such as phase in (introduce gradually) and phase out (withdraw gradually). Phased can also describe something arranged in steps, such as a phased rollout.
What is the difference between phased vs fazed?
Fazed is about feelings, while phased is about stages. If a person is bothered, rattled or thrown off, the word is fazed. If a plan, product or policy happens step by step, the word is phased.
Try a quick swap test. If you can replace the word with “bothered,” use fazed. If you can replace it with “staged” or “step by step,” use phased.
Is it “unfazed” or “unphased”?
Unfazed is the standard spelling for unbothered, because it comes from faze. Unphased is common online, but it is usually treated as a mistake when it means calm or unruffled, since phase refers to stages, not nerves.
Use unfazed in formal writing. The same logic applies to “didn’t faze me,” which is correct, versus “didn’t phase me,” which is not.
Where do you see phase and phased in everyday writing?
You will see phase in project plans, news and science. Common examples include a phased rollout, a phase-out of old technology, a phase of the moon, and a child going through a phase.
In every one of these, the idea is stages. None of them is about being bothered, which is your clue that fazed is the wrong word there.
