What does copybook mean?
A copybook is a book of printed or written models of fine handwriting, once central to education in English-speaking countries. Schoolchildren would sit with a copybook open before them and reproduce its exemplars — often ornate copperplate script — line by line, aiming to match the model's elegance without smudging or error. Because a stray ink blot ruined a carefully kept page, the phrase 'to blot one's copybook' arose, meaning to damage an otherwise unblemished record through some lapse or misconduct; it remains current, especially in British English, applied to sportspeople, politicians, and public figures whose good reputations are suddenly tarnished. Though the literal object has all but vanished from classrooms, replaced by modern pedagogy, the word endures in this figurative sense, evoking discipline, neatness, and the high Victorian ideal of flawless penmanship.

'To blot your copybook' means to spoil an otherwise spotless record — because in Victorian schools, an ink blot was literally a stain on your best page.

Etymology of copybook
The word copybook is formed simply from 'copy', meaning a model to be reproduced, and 'book', and emerged in the late eighteenth or early nineteenth century as printed handwriting manuals became widespread in schools. It belongs to the broad family of English compounds built on 'copy', which itself derives from the Latin 'copia' (abundance), via Old French 'copie'. Its figurative idiom developed within Victorian schooling culture, where the physical condition of one's copybook stood proxy for one's character.
How copybook is actually used
The literal sense (a physical handwriting-practice book) is now largely historical, surviving mainly as an antique or educational curiosity; the figurative sense, especially in British English, keeps the word alive in idioms such as 'blot one's copybook'. The figurative use carries a mildly old-fashioned, formal tone.
