How to use “unfazed” with prepositions

Unfazed is most commonly followed by by to describe something that does not affect or disturb someone.

Quick answer

The usual pattern is “unfazed by”

Use unfazed by for things that do not disturb, surprise, or worry someone. Unfazed about is sometimes used for topics someone feels calm about. Unfazed at, with, and as are generally not standard complements after unfazed, though at can appear separately as a place or time expression.

She seemed unfazed by the criticism.
He is surprisingly unfazed about the delay.
The team remained unfazed by the pressure.

Choose the pattern by meaning

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
unfazed by + thing

Showing what does not affect someone

This is the standard and most natural pattern.

Investors were unfazed by the market drop.
She stayed unfazed by the noise outside.
2
unfazed about + topic

Being calm about a situation

This pattern is less common but natural when referring to a topic or situation.

He sounded unfazed about the interview.
They were unfazed about the rumours.
3
unfazed at + place/time

Using at as a separate adjunct

At normally does not complement unfazed directly. It can introduce location or time information instead.

She remained unfazed at the meeting despite the tension.
He looked unfazed at midnight after the long journey.

See the difference in context

The same subject can take different constructions because each sentence answers a different question.

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using with instead of by

With is not the normal preposition after unfazed.

✕ She was unfazed with the criticism. ✓ She was unfazed by the criticism.

Using at for the cause

At usually marks place or time, not what caused the reaction.

✕ He was unfazed at the news. ✓ He was unfazed by the news.

Confusing about and by

By is more natural for the thing that has no effect.

✕ They were unfazed about the loud noise. ✓ They were unfazed by the loud noise.
