KK: /ɪˈdɪktəl/
Relating to or resulting from official orders or proclamations.
The king issued an edictal decree that changed the laws of the land.
Edictal is derived from "edict" (from Latin "edictum", meaning something proclaimed or announced) and the suffix "-al" (meaning pertaining to). The word "edictal" refers to something that is related to or characteristic of an edict or proclamation.
Think of an 'edict' as a formal announcement, and the '-al' means it pertains to that announcement. So, 'edictal' describes something related to a proclamation.
