Opposing or rejecting hierarchical organization or the principle of ranking things in order of importance or authority.
From anti- (against) + hierarchic (of or relating to hierarchy). This variant form of 'antihierarchal' uses the -ic suffix instead of -al, both coming from the same Greek roots meaning 'sacred rule.'
Both antihierarchic and antihierarchal mean the same thing, but 'antihierarchic' sounds more technical—scientists often use the -ic version when they're being extra formal and academic about rejecting authority structures.
