nominative singular feminine of anicca (adj), or indeclinable particle iti appended
Analysis. anicca (impermanent) + iti (thus, so); the feminine nominative aniccā (impermanence as a quality or fact) followed by the quotative particle iti, forming an abstract noun or exclamation used in doctrinal contexts to denote impermanence as one of the three marks (tilakkhaṇa).
Etymology. a- (not) + nicca (permanent, lasting); nicca is related to Sanskrit nityá- (eternal, perpetual), from the root √ni/√nī (to lead, bind, hold firm), cognate with English nether and German nieder in their sense of downward fixity. The negation a- strips away this sense of duration, emphasizing the opposite: what is not held, not bound, not lasting.
