In Inuit culture, sipiniq (Inuktitut: ᓯᐱᓂᖅ; West Greenland Inuttut: sipineq, from sipi meaning "to split", plural sipiniit)[1][2] refers to a person who is believed to have changed their physical sex as an infant, but whose gender is typically designated as being the same as their perceived original sex.[3] In some ways, being sipiniq can be considered a third gender.[4] In Inuit Nunaat this concept is primarily attested in areas of the Canadian Arctic, such as Igloolik and Nunavik,[5] as well in Greenland such as Kitaamiut Inuit and Inughuit, though Iiviit used the words tikkaliaq and nuliakaaliaq.[2] The Netsilik Inuit used the word kipijuituq for a similar concept.[6]
