Morphology

Dewey + decimal + classification

The components 'decimal' and 'classification' transparently indicate a system of classifying items using a decimal-based scheme, so a learner who knows those words can infer a general meaning. However, the proper name 'Dewey' refers to a specific eponymous library system (three-digit numbers for books) and that library-specific application and conventions are cultural/encyclopedic knowledge not predictable from the words alone, so the expression is only partially transparent.

Etymology

Dewey decimal classification comes from Melvil Dewey, a librarian who in the late 1800s made a simple system to sort books by number. He gave each subject a three-digit code and extra numbers after a dot, so books looked like they had address numbers on their spines — that's why the phrase means 'a way to organize books' in libraries.
