Past: privatized
Past Participle: privatized
Privatize → It is formed from "private" (from Latin *privatus*, meaning belonging to oneself or personal) and "-ize" (a suffix used to form verbs meaning to make or to become). The word "privatize" means to make something private or to transfer ownership from public to private control.
Think of something that becomes 'personal' ('private') when it is 'made' ('-ize') — that's why privatize means to make something private.
