This is you, this is your family tree, and this is your family tree explained.

You have parents, and your parents have parents.

These are your grandparents who also have parents, your great-grandparents.

Keep adding parents, keep adding greats.

For every G in the name, there is one generation in between you and that person.

Grandparents, one G, one generational in-betweener.

Great-great-great-great-grandparents? Four G's, four in-betweensers.

Continuing with the basics, you have siblings and so do your parents. These are your aunts and uncles.

Up the tree, you may call these people your great-ants and uncles, but your grandparent siblings are really your grand

aunts and uncles.

Greats are reserved for the levels above grand.

Your great-grandparents siblings are your great grand aunts and uncles.

Now down the tree, your siblings' children are your nieces and nephews, collectively nibblings,

and you are their aunt or uncle.

Their children are your grand nieces and nephews, and you are their grand aunt or uncle.

We've gone up and we've gone down, and now it's time to go sideways.

When you get married, you get everyone's favorite in-laws.

You're on the same level of the family tree as your spouse's siblings.

You're a kind of pseudo-sibling. All the new family's relationships to you are the same as to your spouse, but they get the in-law prefix.

It's pretty straightforward except for one case. Your spouse's siblings are your siblings-in-law, but are your siblings-in-law's

also your siblings-in-law? It's a little unclear. All right, enough with the in-laws, it's on to the reason you're probably watching this video.

Cousins.
