no tl;dr for this one either
All familial terms and designations can be broadly placed in two categories: blood terms, and bond terms. Blood terms are technical terms, they are words that indicate the nature of the relationship, such as ‘mother’ being the woman who bore you, or ‘brother’ being one with whom you share a set of two parents. Bond terms are more commonly used as addresses, terms you use to for people who are close to you, with whom you have a good relationship.
Blood Relation Terms
Note that the term here for cousins is a collective plural term, not a specific designation for a single cousin. To refer to a cousin, generally ‘father’s/mother’s niece/nephew’ is used instead.
Extended Family Prefixes
One or more of these 5 prefixes can be attached to the terms above to specify the relationship further. They are attached by the following rules:
Birth order number (within that generation) is attached if applicable (exempt for step relations)
One of the ‘Greater’, ‘Lesser’, or ‘Grandchild’ prefix is attached first if applicable
One of the ‘Half’ or ‘In-Law/Step’ prefix is attached second if applicable
The term itself is then attached
All these prefixes are attached by the morpheme boundary.
Note that using the ‘Greater’ and ‘Lesser’ prefix is basically saying ‘father’s’ and ‘mother’s’ respectively.
To keep this post short-ish, I’ll leave examples in an appendix page.
Bond Relation Terms
These terms are not technical, and are only used should you feel the spirit of the word. For instance, a child who was abandoned by his birth mother and raised by an aunt might call that aunt “hesorth” (bond term for ‘mother’), but cannot call her “hersof” (blood term for mother). They are generally stand alone terms, except in the case where the person to whom you are referring is younger than you, in which case the “ke” prefix is attached (without the morpheme boundary).
