And conversely, there are languages with different words for "father's sister" and "mother's sister", and for male vs female cousins, etc.

And we don't even have to get exotic for that. My language, Danish, is just a run-of-the-mill Germanic language and those terms are "faster", "moster", "fætter", and "kusine".
Some of the East Asian languages are crazy regarding terms for family members. It's like learning foreign words for plants: I just give up. I will not even attempt to learn them.
There are also languages where the relative age difference changes how you address a relative. Like if your father is older or younger than their sibling, the way your address that uncle or aunt changes. There is another way you address them if they are the oldest or youngest uncle/aunt. Similar but slightly different on the mothers side.
