A sister is someone very close to a person – often that person’s sister, but it can also be anyone close to the person in question. A sister is usually a female person or child who shares either one or both parents with another person. The male equivalent is a younger brother. While the word typically refers only to familial relationships, sometimes it can be used in fixative terms to describe non-familial relationships as well.
A first sister is simply a female offspring who is also a direct descendant of the same biological parent. If one sister has a child and a sibling, then that child will automatically become the mother of another offspring. The second sister would then become a daughter-in-law. In rare cases, brothers do not share the same mother, which will also make them first cousins.
In comparison to younger siblings, older sisters are generally closer in age and often share a similar culture. An older sister will often be a cousin to her sibling, which can result in more genetic relatedness. Some younger siblings are not genetically related to each other at all. These younger siblings can share a great deal more in common with each other, but they are not related by blood.
A nikolaevna or grandsonship sister, on the other hand, is not related by blood to her brothers and sisters. A nikolaevna is also referred to as a “princess” in some cultures. However, in contemporary Russian culture, a nikolaevna is the equivalent of a duchess, and the title comes generally earned through marriage.
Conjoined twins, who are technically referred to as sisters, do not have their own bloodline. The term conjoined twins is used to describe any two people who are technically one half of one person. For example, a girl may be adopted from foster care and called a half sister, or she may have been born with two heads and was raised as a single person. In certain countries where historical records are sparse, the term conjoined twins is used interchangeably with sister. However, in modern Russian culture, when referring to older women, the term for a girl who is adopted as a foster child and then married is “sister”.
Conjoined twins have made their mark on history. They have played major roles in popular culture, ranging from royalty to cult pop stars. Their existence in present day society has inspired a plethora of TV shows and books, as well as inspiring numerous fictions and nonfiction works. As a result, they have become a very important part of Russian culture, with many famous people bearing their name, including Russia’s first lady, Mrs. S. Elvira; Russia’s most popular reality TV star, Dmitry Chaplin; the lead singer of Aerosmith, Phil Collins; and the ex-Duchess of York, Elizabeth Parke Custis.
