relative clause with several parts

[Martimart]

Dear forum members,

I have a questions about the following sentence:

"Is Anna, who is 24 years old and [who is] a student, your sister?"

I am sure there are better ways to ask this question, but if one wanted to use this kind of construction with two relative clauses, would it be necessary to write the second "who is" or could it be omitted? I'm referring to the part in the square brackets.

From a grammatical point of view, is there anything else wrong with this sentence?

I have the same questions about this sentence:

"Is Anna a student who is 24 years old and [who is] your sister?"

I couldn't find the answer to these questions in any of my ESL textbooks or on the internet, so I would really appreciate an answer from one of you guys? Any pointers as to where I can look up applicable rules would also be appreciated.

Thanks,

Martin

would it be necessary to write the second "who is" or could it be omitted? -- It should be omitted. It is not necessarily an elided clause anyway. It is just part of a compound predicate.

From a grammatical point of view, is there anything else wrong with this sentence?-- Grammatically, no. Stylistically it is poor and semantically it is unrealistic.


"Is Anna a student who is 24 years old and [who is] your sister?"-- No good.
