A preservative is a substance put into something so it does not go bad so quickly — food in a packet, or wood so it does not rot. On food labels you will see the word; some try to avoid “preservatives” and buy fresh. Though actually, almost all long-life food has some, and salt, sugar, and vinegar are old, ordinary preservatives too, not only factory chemicals. The word is also an adjective: a preservative chemical. It is a practical, slightly technical word you meet in shops and on packaging more than in stories. Do not mix it up with a (a person who saves old buildings) or with jam called a preserve.
組成From Old French preservatif, from Medieval Latin praeservativus, from the same family as preserve (to keep from going bad).
