Denationalize → It is formed from "de-" (meaning down, away, or reverse) and "national" (from Latin "natio" meaning birth or nation) and the suffix "-ize" (meaning to make or to become). The word "denationalize" means to remove the national status or identity from something, effectively reversing its national affiliation.
Think of 'removing' ('de-') the 'national' identity from something — that's why denationalize means to take away its national status.
