Morphology

codebook = code + book (transparent) = code + book

Compound formation is straightforward; the technical sense is a specialized application but still literally a listing/table of codewords.

Etymology

Codebook is made from code and book, with code coming from codex meaning 'book'. So a codebook is like a 'book' or list of codewords used to match and change data, which is why engineers and researchers use it to convert, compress, or read coded information.
