IPA: /əˈfɪkʃəl/
KK: /əˈfɪkʃəl/
Relating to a part of a word that is added to its base form, such as a prefix or suffix.
The affixial nature of the word changes its meaning significantly.
Affixial is formed from "affix" (from Latin "affixare", meaning to fasten or attach) and "-ial" (a suffix meaning relating to or characterized by). The word "affixial" refers to something that is related to or characterized by affixing or attaching.
Think of 'affix' meaning to 'attach' and '-ial' indicating a relation — so affixial means relating to attaching.
