IPA: //ʌnˈkænɪkəl//
KK: /ʌnˈkænɪkəl/
Not conforming to the accepted standard or rule; not part of the official or recognized set.
The author's work was considered uncanonical because it did not follow traditional narrative structures.
Uncanonical → It is formed from "un-" (meaning not) and "canonical" (from Greek "kanonikos", meaning according to rule or standard). The word "uncanonical" means not conforming to established rules or standards.
Think of 'not' ('un-') following the 'rules' ('canonical') — that's why uncanonical means something that does not follow the established rules.
