KK: /ˈbʊkˌwɜrm/
A person who loves to read a lot and spends a lot of time doing it.
As a bookworm, she always has her nose in a book during her free time.
Bookworm is formed from "book" (from Old English "bōc", meaning a written work or text) and "worm" (from Old English "wyrm", meaning a small creature or insect). The term describes someone who is very fond of reading, as if they are consuming books like a worm would consume material.
Think of a 'book' as a written work and a 'worm' as a creature that consumes. This helps you remember that a bookworm is someone who loves to read and devours books.
