Origin: 1325–75; Middle English preserven < Medieval Latin praeservāre to guard (Late Latin: to observe), equivalent to Latin prae-pre- + servāre to watch over, keep, preserve, observe
late 14c., from O.Fr. preserver, from M.L. preservare "keep, preserve," from L.L. præservare "guard beforehand," from L. præ- "before" + servare "to keep safe" (see observe). The noun sense of "fruit preserved with sugar" is from c.1600; that of "protected place
for animals or plants" (a sense more properly belonging to conserve) is from 1807. Preservationist "advocate of protecting historic property" is recorded from 1927. Preservative (adj.) is attested from late 14c.; the noun sense of "chemical added to foods to keep them from rotting" is from 1875.
