First cousins can be classified in two ways: patrilateral or mattilateral and cross cousins or ortho. While ortho-cousins (also called parallel cousins) are the children of two brothers or sisters; Cross cousins are the children of a sister and a brother. Someone is your patrilateral cousin if you are a first cousin by your father (and your father`s brother or sister); Someone is your matrilateral cousin if you are first cousins by your mother (and your mother`s brother or sister). Example 2: A friend asked me to help him understand his relationship with his mother`s great-grandson. On the table above, you would place my friend at B2, his mother at B1 and his aunt at C0. That`s why the aunt`s great-grandson is at C3. My friend B2 and his relative C3 are second cousins once they have been abducted. A rarer use of the term is seen in “casual conversations” with the term brother-in-law describing the relationship between the brother-in-law: William`s brother, Charles, has a brother-in-law named James (James is Charles` brother-in-law here, not because he married his sister, but because he is a brother of Charles` wife), James referring to William as his brother-in-law.  Deleted: Distance by degree in the relationship; as a cousin who has already been abducted; means of different generations. The words “once removed” mean that there is a difference from a generation. Deleted twice means that there is a difference of two generations. etc.
Brothers-in-law and sisters-in-law also refer to the reciprocal relationship between a person`s spouse and the spouse of his or her siblings. In Indian English, we can speak of co-brothers and sisters (specificity of a co-sister, for the wife of the brother-in-law, or co-brother, for the husband of the brother-in-law). Death: For example, if your husband dies, are his sister`s children still your nieces and nephews? Almost everyone would agree that they are. They won`t stop calling you “Aunt Helen,” presumably. Brother-in-law: The brother of the man or woman; also the sister`s husband; Sometimes the husband of the wife`s sister. (Top of Page) Summary: The English language has a whole range of relationship or kinship terms that can surprise even native English speakers. What is the difference between a second cousin and a first cousin once abducted, or a half-sister and half-sister, not to mention an orthopedic cousin and a cross cousin? This page demystifies some common and unusual terms with diagrams. Adoption: The rule here is simple: if you are not a member of a European governing body, someone who has been adopted is just as much a parent as a parent born into the family. Whether your sister adopts a little girl or gives birth to her, that little girl is your niece. Whether or not little Jennifer knows she has been adopted, you are her aunt Helen and she is your niece.
You wouldn`t call her your adoptive niece, implying that she`s not your “real” niece. These are the only really delicate terms of the in-laws. “Brother-in-law” and “sister-in-law” each have two or three meanings. All authorities agree on the first two meanings, but there is some controversy over the third (and personally, I don`t care). If you need to clarify the relationship, you can always use a few extra words. “My ex-husband`s half-brother” is much more accurate and accurate than “my brother-in-law,” but if you and he have a good relationship, there`s nothing wrong with talking about each other as brother and sister-in-law. The only exception, of course, is that divorced spouses can no longer call themselves “husband” and “wife,” but must use “ex-husband” and “ex-wife” (informal, just “ex”), no matter how consensual the divorce is. By the way, “half-brother” and “half-sister” are always written as individual words, without hyphens. “Half-brother” and “half-sister” are each written in two words (source: AHD4). Isn`t English a strange language? The word “deleted” is only used if the relationship involves going down the family tree to later generations. For example, B2 and C4 are second-degree cousins who have been abducted twice, not fourth-degree cousins who have been abducted twice.
Aunt: The sister of the father or mother; — correlates with the nephew or niece. Also applied to an uncle`s wife. (Top of Page) Example 1: What is the relationship with Joe, the great-grandson of your mother`s cousin? Answer: In the table above, cousins B1 and C1 must be your mother and cousin. (If a relationship is only specified as a “cousin,” it usually means “first cousin.”) You are then B2, your mother`s child. Your mother`s cousin is C1, and her great-grandson Joe would be C4, three generations below her. They (B2) are second-degree cousins of C2; Joe is removed two or two generations below C2. So your mother`s [first degree] great-grandson is your second cousin who was abducted twice — and of course, you`re also her second-degree cousin who was abducted twice. Divorce: This is the most difficult area. Of course, if you and your husband divorce, his mother is still your grandmother, but is she still your mother-in-law? Some people would say yes; Some would say no. Judith Martin (in Miss Manners` Guide to Extrociatingly Correct Behavior; Atheneum, 1982; Pages 565-6) promotes a certain creative ambiguity, particularly in everyday language. Especially if you have a good relationship with them, regardless of your relationship with your ex-husband, there`s no reason why you can`t keep calling his children your nieces and nephews, or why they shouldn`t keep calling you Aunt Helen.
Here`s the first case: Lucy and Ethel are sisters, and Fred and Ricky are brothers. Jack and Jill are double cousins of the first degree. As they are children of brothers and children of sisters, they are double first cousins of orthopedics. .
