I'm confused about using "has" or "have" after "who". For example:

  1. I am a doctor who have confusion in using has or Have.
  2. I am a engineer who has 4 year experience, degree in engineering and is available.

Will it vary depending on I or Who?

    Also as a note: sentence 2 needs an an before engineer, an a before degree, and some clarification after available. Something like: and is currently available for work.

  • Who is third person, so even if it refers to a first- or second-person (I, you) it takes third-person agreement (singular {-Z}, plural {-Zero}) in the present tense. Aug 31, 2014 at 15:11

I am a doctor who has a treadmill.

We are doctors who have an X-ray machine.

I am a professor who has a tweed jacket.

We are professors who have published three papers.

The verb after who should match the object before who. (In the sentence structure you use, the subject [I/We] is independent of the object [professor/professors]):

I know a professor who has grey hair.

We know a professor who has mismatched socks.

I know two plumbers who have leaky sinks.

We saw three mathematicians who have proctectors in their pockets.

To quickly double-check your verb choice, simply remove the subject, predicate, and the who, and make sure it reads correctly:

"We know a doctor who have a new car," becomes "A doctor have a new car." (WRONG)

"We know the nurse who has a new sofa," becomes "The nurse has a new sofa." (RIGHT)


In both your examples, the correct answer is has.

The word has refers to the doctor or engineer, not to I.


It should be has in both the places. The second sentence should have an Engineer I feel
