Proper name-like uses are much more frequent with certain kin terms, notably the ones that denote ascending relations, and in particular parental ones, such as ‘father’ and ‘mother’.
Standardized
IF any other kin terms are used like proper names, THEN those denoting ascending relations, and in particular parental ones, such as ‘father’ and ‘mother’, are used like proper names too.
For example, in the English-speaking world, one would address one’s father as ‘father’ but one’s siblings or children rather by their names. Accordnig to Dahl & Koptjevskaja-Tamm, a system which is inverse to the English one is not attested. This suggests a universal partial ordering of kin terms (‘hierarchy’ being too strong), based on closeness to what Dahl & Koptjevskaja-Tamm propose to call the PARENTAL PROTOTYPE. Parental terms were singled out already in Greenberg’s work on markedness relations (see # 1662).
