Major Difference Between Niece, Nephew And Cousin



In bloodlines and legal relationships, Nephew and Niece refer to the same familial relationship: the child of one’s sibling (brother or sister). But nephew is the term for males and niece for females. In other words, if you have a niece or nephew, you are their aunt (female) or uncle (male). They are just one generation level down from you. Cousins on the other hand are the children of your aunts and uncles. 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.
