Everyone has a family, but did you know that there are different family words that you should use to describe a member? In this article, we’ll go through different family relationship terms.

Extended Family

Extended families are those related to you but aren’t a part of your nuclear family (mom, dad, siblings). For example, your mother’s sister is your aunt, which makes her a part of your extended family. Other examples of extended family are cousins, grandparents, and uncles.

Culture and lifestyle often determine how often you see your extended family or how close you are to each other. In some cultures, all family members feel like immediate family, while in others, time with extended family might only be at holidays and family reunions.

Immediate Family

Immediate family is confusing when defining family words. It’s often confused with the nuclear family; however, it has a different meaning. Your immediate family is those who are closely tied to your everyday life and not far from you in your family tree.

Although that may look different for everyone, in general, you can define immediate family as your spouse, parents, children, grandparents, and the spouses of that group. Half-brothers, half-sisters, step-siblings, and step-parents are immediate family as well.

Siblings

If you have at least one parent in common with someone, they are your sibling. Siblings are a brother or sister, half-brother or half-sister since either the father or mother or both are a blood relation.

Step-siblings occur when two people get married and both have children from other relationships. Although a step-sibling is a form of a sibling, they aren’t a blood relation sibling. You become siblings because of the marriage.

In-Laws

In-laws are the other family words that don’t include a bloodline in the relationship. You gain in-laws through marriage. For example, when you marry someone, their parents become your mother-in-law and father-in-law. Their siblings become brothers-in-law and sisters-in-law. The name stems from the fact that you are now brother and sister by law rather than through blood.

The subject of much humor in TV shows and movies, in-laws can be fun and lovable. On the other hand, adapting to in-laws is sometimes tricky. Essentially, in-laws are spouse’s relatives. They could be parents, siblings, or the siblings’ own spouses. Sometimes, parents of spouses can refer to each other as in-laws, but this definition traditionally applies more narrowly.

Brother-in-Law

A brother-in-law is 1) a spouse’s brother, 2) a sibling’s husband, or 3) a spouse’s sibling’s husband. As the word explains, this is not a blood relative but a “brother” by virtue of marriage. When the marriage dissolves, so does the in-law relationship. On the other hand, some longstanding brothers-in-law become as close as actual brothers.

Sister-in Law

In the same way, a sister-in-law can be 1) a sibling’s wife, 2) a spouse’s sister, or 3) a spouse’s sibling’s wife. As with brothers-in-law, emotional closeness depends on marriage longevity, circumstances, and individual temperaments. Famous sisters-in-law include Jackie and Ethel Kennedy, whose respective husbands were brothers John and Robert Kennedy.

Nephew

Nicholas Gage is a nephew to actress Talia Shire and to director Francis Ford Coppola — Gage is actually his stage name. A nephew is either the son of a sibling or the son of a spouse’s sibling. Sometimes, people raise nephews (and nieces) as their own children in the event of the child’s parent(s) death or absence.

Household

Household is one word related to family with broad cultural and financial implications. It can refer to an immediate family of parents and their children. Alternatively, a household can be an extended family — multi-generational — living under one roof. Thirdly, it might signify non-relatives living together. It is a broad example of family-related vocabulary.

Ancestor

An ancestor is anyone from a prior generation with whom you can establish a genetic link. So, an ancestor could be a parent or grandparent. However, this word usually associates with earlier generations, as those that appear when you trace a family tree. The vital factor is that a blood connection must exist, no matter how far back the ancestor goes.

Step-Brother

When one parent of a child marries someone different from the other parent, the new spouse might bring children into the family. If that newly-minted husband or wife has a son, he becomes a step-brother to the child. Not related by blood, a step-brother may nevertheless have a legal tie to his step-siblings, depending on age and living arrangements.

Child

What, then, is a child? It is a son or daughter of two people that results from natural conception and birth or, otherwise, the product of legal adoption. This word can apply to an adult or a minor. State laws vary concerning children in terms of support, custody, or — with regard to adults — power of attorney and inheritance.

Grandparents

A grandparent is a parent of your mother or father. You have parents, and your parents have parents. Believe it or not, they were young once too. So, if you have someone in your life who you call grandma or grandpa (or something to that effect), they are probably a mom or dad to one of your parents. You may also have step-grandparents in your family if there is a second marriage for one or both parents.

Niece/Nephew

When your brother or sister has a child, that child is your niece or nephew. A niece is a female offspring of a sibling, and a nephew is a male offspring of a sibling. When this occurs, you become an aunt if you are a woman and an uncle if you are a man. You can have any number of nieces or nephews, depending on how many children your siblings have.

Cousin

Now that you understand what a niece or nephew is, it’s easier to understand what a cousin is. If you are a niece or nephew to an uncle or aunt, the children of that uncle and aunt are your cousins.

So, if Aunt Jane has two kids, you have two cousins. People often assume a cousin will be close to their age; however, that isn’t always the case.

The age gap between siblings affects how far apart you will be from a cousin. If your mother has a sister (your aunt) who is 20 years older than her, and she had a child before you were even born, that cousin will be older than you.

In some families, children naturally call adult cousins aunts or uncles if the age spread is many years and the cousin is an adult while they are still a child. It can get confusing. When in doubt, if the person was born to a parent’s sibling, they are your cousin.

In the lineage of a family, there are often many cousins. You can have cousins from previous generations who you never met. The line of cousins in any family goes back through grandparents and their offspring.

Spouse

A spouse is a family word that refers to someone that is not blood-related. Instead, it is a person’s partner in life, usually through marriage. You may hear terms like “better half” or someone’s “mate.” The proper term is spouse; however, the most common forms of spouse that you likely hear are husband and wife.

During a lifetime, one may have multiple spouses (not at the same time) due to divorce, death, and remarriage. There isn’t a limit to how many spouses you can have as long as they are legally separate unions.
