What does bookmaker mean?
A bookmaker is a person or business that accepts bets on the outcomes of events — most famously horse races, but also football matches, political elections, and other contests — setting the odds at which wagers are taken and paying out to winning customers. The name derives from the practice of recording wagers in a physical book, known as the bettor's 'book'. In Britain and Ireland, licensed bookmakers (colloquially 'bookies') are a familiar, regulated fixture of high streets and racetracks, trading under names such as William Hill and Ladbrokes; in the United States the word can suggest informal or illicit gambling, since legal operations are typically called sportsbooks. The bookmaker's craft lies in pricing risk: by balancing the money wagered on each outcome and building in a margin, the house aims to profit regardless of the result. A related historical sense refers to one who makes or binds books, though this meaning is now rare.

Etymology of bookmaker
The word 'bookmaker' is formed from the noun 'book' plus the agent suffix '-maker', first appearing in English in the early modern period. Its original sense referred literally to someone who made books — a binder or producer of volumes — and by the seventeenth century it had come to mean a person who kept a book of wagers, recording bets as entries in a ledger. It shares its root with other compounds built on 'book', such as 'bookkeeper' and 'bookworm', all ultimately deriving from Old English 'bōc'.
How bookmaker is actually used
In British English, 'bookmaker' is the formal term for what is colloquially called a 'bookie', and the trade is legal and heavily regulated; in American English the word often carries connotations of illegal or informal gambling, where legal sportsbooks are more commonly called sportsbooks. The older sense referring to someone who physically makes books is now rare and largely historical.
Easily confused with bookmaker
Bookie is simply an informal term for the same person — a bookmaker — so the words are interchangeable rather than distinct in meaning.
