IPA: /ˌæntɪˈkɔːpəreɪt/
KK: /æntiˈkɔrpərɪt/
Describing a stance or attitude that is against corporations and their practices.
The anticorporate movement seeks to challenge the influence of large companies on society.
Anticorporate is formed from "anti-" (meaning against) and "corporate" (from Latin "corporatus", meaning formed into a body). The word describes a stance or attitude that is against corporate entities or practices.
Think of being 'against' ('anti-') something that is 'formed into a body' ('corporate') — that's why anticorporate means opposing corporate structures.
