I'm not a speaker, but someone once explained to me that for example in Farsi, you can't just refer to someone's "cousin", without knowing the person's gender _and_ the two related parents genders.
Let's say that a character in book 1 suspects his cousin of committing a murder, and nothing else is revealed about that cousin (let's say it's a side plot) until book 5, where new evidence turns up and he is suddenly found guilty. If you differentiate between male and female cousin, how do you translate book 1 if book 5 hasn't been written yet?
Even better, let's assume the books are finished, the author is dead, but you're translating to a language that differentiates between younger/older cousins / cousins on different sides of the family. You just pick whichever word you like more. Ten years later, Hollywood makes a movie adaptation, and the "male cousin" from your translation is played by none other than Angelina Jollie. Your readers are very confused.
Translation is hard.
If you speak Chinese, there is a specific word for this relationship.
Relationship labels should capture the actual labels people routinely use.
Apple does not offer this label to English-speakers, unless you have Chinese as one of your additional languages.
Similarly, if English is not one of your languages, the label for “cousin” will not appear, which is localized in an even more convoluted way in Chinese.
If you have a contact with that specific option set, it'd display as
>younger cousin (mother's sibling's daughter or father's sister's daughter).
EDIT: I see, there were two questions asked, saagarjha answered “yes”, but you’re answering the first question “is this just cousin”.
You are correct that it’s not just cousin, sorry for the correction!
In US, separating out "younger sister" is weird, they probably should collapse the list. But in others like Chinese, some of the collapsed relationships have different words.
Many Asian cultures, including Chinese, have a wider variety of kinship terms than English. The (unwieldy) name of this constant describes one such relationship which doesn't have a direct equivalent in English.
The first 2 letters of the string make it obvious:
"CNLabelContactRelationYoungerCousinMothersSiblingsDaughterOrFathersSistersDaughter"
"CN"
These labels are often used in Chinese & similar relationship models. It comes from the dual consequence of tightknit multi-generation families & a dense symbol-derived language. In Chinese, you can derive the term for a given relative within 2 characters using this relationship model.
At the top there's a black bar that shows hierarchy of where this object is coming from:

This seems to represent two different relationships. The mother’s sibling could be a brother. For the father a sister is specified. What about the father’s brother’s younger daughter?
The description says younger daughter in both cases but the name doesn’t specify. So what’s the class for the older daughter of the mother’s sibling or the father’s sister?
And if age is relevant what about the father’s older sister’s younger daughter, etc.
