Etymology

Origin of contract

First recorded in 1300–50; Middle English noun contract, contrait, from Old French, from Latin contractus “undertaking a transaction, agreement” (equivalent to contrac-, stem of contrahere “to draw in, bring together, enter into an agreement” + -tus verbal noun suffix); the verb is from Latin contractus, past participle of contrahere

Explanation

When you and someone else have agreed on something and that agreement is both binding and enforceable by law, you have a contract. When you rent an apartment, you and your future landlord sign a rental contract. You can also use the word in this sense as a verb meaning "to hire." Wouldn't you like to contract someone to clean your room for you? In other verbal uses of contract, place the accent on the second syllable — kun-TRAKT. If you contract a disease, you catch it, but only use this if it's something serious. You catch a cold, but contract malaria. Contract also means "shrink." When the economy contracts, consumers stop buying things, and people lose their jobs.
