from A transparent English compound: the prefix 're-, 'again' or 'back' (from Latin re-), bolted onto 'entry,' which descends through Old French entree from Latin intrare, 'to go in' (from in, 'into,' plus the root of trans, a threshold-crossing). The space-age sense — the fiery atmospheric kind — is a 20th-century addition, born with rockets that first had to leave before they could so violently come back.
