Talk:-ic

"Anglomania +‎ -ic" but "Anglo- +‎ -maniac"
Why are the etymology of those two words defined by different suffixes? That is, why is there -maniac but not -manic? --Backinstadiums (talk) 17:18, 18 November 2019 (UTC)

-tic
for example hubristic from hubris --Backinstadiums (talk) 16:09, 26 November 2019 (UTC)
