IPA: /əˈfaɪnəl/
KK: /əˈfaɪnəl/
Relating to a family connection that comes from marriage rather than blood, such as a relationship with in-laws.
She has affinal ties to the family through her marriage.
Affinal is formed from "ad-" (meaning to) and "finis" (meaning end or boundary). The term refers to relationships that are established through marriage or alliance, thus connecting families or individuals beyond blood relations.
Think of 'to' ('ad-') and 'boundary' ('finis') to remember that 'affinal' describes relationships that extend beyond blood ties, like those formed through marriage.
