What is the relation name for my wife's sister's son's wife?

  • 1
    My nephew's wife? (Or if you want to be stuffy about it - my nephew-in-law's wife). :-) Aug 16, 2016 at 18:11
  • English doesn't have specific names for most possible relations. You have to stack up the basic ones. Aug 16, 2016 at 18:19
  • "My sister-in-law's daughter-in-law"

    Welcome to EL&U. I would say niece-in-law, but others would say there is no relation at all. See Paucity of words for relationships.

    Thanks for these good answers. I like simplicity. I think I would feel most comfortable introducing her (or thinking of her) as my nephew's wife. Aug 16, 2016 at 18:40

For the sake of simplicity, call her your niece. If, for some reason, you are inquired as to which side of the family she belongs, then feel free to go into detail.


So here's Bob, a married man whose wife Norma has a sister Ellen.

Ellen is Bob's sister-in-law. Cool.

Ellen's son, Phil, is Norma's and Bob's nephew; they are his aunt and uncle.

Phil gets married to Kim. Kim is Ellen's daughter-in-law, and Bob's and Norma's niece. Forget the "in-law" construct; it's clumsy.

    Welcome to ELU, can you please add sources to your answer to substantiate your claim. You can also have a look at the help center to find out about good answers. Especially a reference supporting the referring to a such a person as a niece would be great.
