Major Difference Between Niece, Nephew And Cousin

Meaning And Examples

The term “niece” refers to a female relative who is the daughter of one’s brother or sister. In other words, she is the child of one’s sibling. The relationship between an individual and their niece is based on a blood connection through a common parent.

For example, if John has a sister named Mary and Mary has a daughter named Emily, then Emily is John’s niece. The same applies if John has a brother named Peter, and Peter has a daughter named Sarah. In this case, Sarah would also be John’s niece.

The term “nephew” refers to a male relative who is the son of one’s brother or sister. In other words, he is the child of one’s sibling.

For example, if Sarah has a brother named Michael and Michael has a son named Alex, then Alex is Sarah’s nephew. The same applies if Sarah has a sister named Lisa, and Lisa has a son named James. In this case, James would also be Sarah’s nephew.

A cousin is a more extended family relationship. Cousins are the children of your parents’ siblings (uncles or aunts). For example, your father’s brother’s children or your mother’s sister’s children would be your cousins. Cousins can also be classified as first cousins, second cousins, etc., depending on how many generations they are removed from your common grandparents.

Cousins, specifically first cousins are people who have the same grandparents. Their parents would be siblings. Though in some cultures and families, it is common to call the child of one’s cousin a ‘’niece’’ or ‘’nephew’’.

You may call a relative a niece or nephew of yours if the relationship is any of the following:

  • Your own blood brother or step-brother or half-brother’s children
  • Your own blood sister or step-sister or half-sister’s children
  • The children of any people who have those relationships (Niece & Nephew) to your spouse.
