The term 'prefix with conservative' refers to three words: neo, ULTRA, and ARCH. Neo is a prefix meaning 'NEW, ' ULTRA is a prefix meaning 'EXTREME, ' and ARCH is a prefix meaning 'chief or principal.' All three of these words are used to describe something that is conservative in nature. For example, a neo-conservative is someone who is NEW to the conservative movement, an ULTRA-conservative is someone who is extremely conservative, and an ARCH-conservative is someone who is the chief or principal conservative.
