A chequebook is a small book of paper cheques that your bank gives you. Each page is one cheque. You write who should get the money, the amount, and the date, then you sign it. The other person takes it to a bank, and the money comes out of your account. This is the usual British spelling: cheque inside the word, not check. In the United States the same book is a checkbook. Banks, offices, and older British and Commonwealth writing still use chequebook quite naturally. Though actually, a lot of younger people hardly touch one now. They pay with a card or a phone. The book is still real, and businesses still use cheques, but in daily life it can feel a little old-fashioned. It is a bank word, calm and formal, not slang.
