bylaw

the word 'bylaw' originates from the old norse term 'bȳjar-lǫg', which literally meant 'town law'. the first element, 'bȳ', referred to a settlement or town, while 'lǫg' was the plural of 'lag', meaning 'law' or 'layer'. it entered middle english as 'bilawe' or 'belage', signifying a local ordinance subsidiary to the general law of the land. over time, the term broadened from its municipal origins to denote any secondary rule or regulation adopted by a corporation, association, or other organized body for its internal governance, preserving the core idea of a rule specific to a particular community or context.

Structure: by (secondary) + law (rule) by (from old norse 'bȳ', meaning town or settlement; in this compound, it denotes a secondary or local context). law (from old english 'lagu', of old norse origin, meaning something laid down or fixed, a rule).
