`== Rare Relationships == ``It is possible to have a sibling that is more than a half sibling but less than a full sibling. For example, if one of the child's parent's dies and the surviving parent marries a sibling of the deceased spouse and they have a child, the two children would be three-quarter siblings to each other. They would share one parent in common but share all four grandparents. Essentially, the two children would be half siblings through one parental line and first cousins through the other parental line.``  :It is my motion that this tract be deleted from the article.  When doing research, it is next to impossible to come across any material referring to this set-up as ``three-quarter siblings.``  Just because you may share all four grandparents in common does not make you any more a sibling to someone than a run-of-the-mill half-sibling.  Your proximity of relationship to your siblings is determined by your parents, and if you share one parent with someone, they are your half-sibling.  Even if your father happens to be the uncle of your half-sister, that is irrelevant for definitional purposes.  Half-sibling is included in this article because it is a widely-used term; three-quarter sibling is most certainly not, as even light research will reveal.     ::Well, it's certainly interesting, and one need only the most basic understanding of genetics to know that such a sibling would certainly share a much closer genetic relationship than normal. If the term isn't used it can simply be written ``three quarter sibling``.    == Sibling Discussion == The link with the Dutch ``Broer`` is not correct. In Dutch you have the words Broer (Brother) and Zus (Sister). But there is no translation for Sibling.    :And some languages don't seem to have words for just brother or just sister. For example, I believe in Thai there's phi-chai (older brother), nong-chai (younger brother), phi-sow (older sister), nong-sow (younger sister). Neither chai nor sow nor chai-sow are used. Phi-nong may be used to refer collectively to ``older and yonger (brothers and sisters)`` or even a group of people.    Say Sue and Jeff each had a half-sister (Mary) in common. However, Sue has Mary's mother - while Jeff has Mary's father. What kind of relationship would that be between Sue and Jeff?   :I'm not sure whether they would even be related at all... — (-||-)   :If I understand your question the way you understand it, then there is no blood relationship between Sue and Jeff and they are classed as step-siblings.    :A former next door neighbour of mine is in the position of ``Mary``, and he has actually had one of his half sisters marry one of his half brothers. (No blood relationship, and raised in different countries)  Lance Tyrell  Why is the Simple English article linking to ``Sister``?  I'm lazy right now, but there is a slang use of ``Bro`` check urbandictionary for full description but its basically (if you live in the 909) black dickies, skin/metalmulisha/srh whatever t shirts , same brand, but tilted hiphop fashion hats and dvs/circa shoes. Also, they are huge douchebags.  == Half-Sibling Discussion == ``A stepsibling ... bears no blood relation`` and ``A half sibling ... is a sibling with one shared biological parent`` contradict ``... many half siblings are stepsiblings and vice versa``.  On a different note, is an adopted sibling considered a stepsibling? :This is completely inaccurate - no step-sibling is referred to as a half-sibling, and no half-sibling is referred to as a step-sibling.  Half-siblings share one biological parent, and therefore if your mother remarries (for example), you do not thereafter refer to a new baby as your ``step-sibling.``  He or she will be your half-brother or sister, and one simply never refers to a half-sibling as a step-sibling.
