What does contract mean?
A contract is most commonly understood as a legally enforceable agreement between two or more parties — whether written, spoken, or implied by conduct — in which each party accepts obligations toward the other. Contracts underpin nearly every commercial and personal transaction, from employment agreements to house purchases, and their terms are typically expected to be honoured on pain of legal penalty, known as breach of contract. As a verb, however, contract has quite different meanings: it can mean to shrink or draw inward (as when metals contract on cooling), to enter formally into such an agreement ('to contract with a supplier'), or to acquire an illness ('to contract malaria'). This duality is reflected in pronunciation: the noun carries first-syllable stress while the verb stresses the second syllable, a pattern shared with many Latin-derived English words. The word derives from the Latin contractus, from contrahere, 'to draw together', which also gives us traction, extract, and retract.
A legally binding agreement between two or more parties that creates mutual obligations enforceable by law.

Etymology of contract
Contract comes from the Latin contractus, the past participle of contrahere, formed from com- ('together') and trahere ('to draw or pull'), literally meaning 'drawn together'. It entered English via Old French around the Middle English period, initially carrying the sense of drawing together or narrowing before establishing itself firmly as a term for binding agreements in legal usage. The same Latin root trahere produced a family of English cognates including traction, extraction, retraction, and subtraction, all preserving the core idea of pulling or drawing. The stress-shift between noun and verb follows a common pattern among Latinate English words borrowed through French.

How contract is actually used
Stress distinguishes the parts of speech: as a noun the stress falls on the first syllable (CON-tract), while as a verb it falls on the second (con-TRACT). In everyday British English, 'contract' can also refer to an arrangement to hire a hitman (a criminal slang sense), though this is informal and context-dependent. The verb sense meaning 'to acquire a disease' is standard in medical contexts.

Contrast means a striking difference between things, whereas contract refers to a legal agreement or the act of shrinking; they differ by one letter but share no meaning.
