@CGCampbell Genitive means possessive. In English, that’s usually just add
’s
to a name (except when it’s just
’
alone), but in other languages, the changes to a word to form the genitive/possessive can be more elaborate. In Icelandic, there are a few different forms for names, and they have corresponding (different) forms for the genitive. Since there isn’t one “universal” (ish) form for genitives like English has with
’s
, if the form of a name isn’t properly formed, there isn’t a corresponding genitive form, which causes a problem with the formation of the patronymic system. —
