Synonym discussion

Sense: noun/1

'Book' is the broad everyday word for a published work that people read. 'Novel' is narrower: it must be a long fictional story. 'Textbook' is written for study and is usually used in school or training. 'Manual' gives practical instructions, such as how to use a machine. 'Volume' is more formal and often refers to one book in a set or series, or simply sounds more technical than 'book'. So you can say 'I bought a book about birds', but 'novel' would be wrong there. You can say 'The repair manual is in the drawer' or 'Volume two explains the war years'.

Etymology

Proto-GermanicOld EnglishEnglish

English 'book' comes from Old English 'boc'. It belongs to a Germanic word family seen in Dutch 'boek' and German 'Buch'. Many historians connect the word with 'beech', because early Germanic people may have carved letters on beech wood or beech tablets. The oldest meaning was the physical written object; from that, English later developed senses for a literary work, a section of a long text, business account records, and finally the verb meaning 'reserve in advance'.
