Selected source glosses provide context, not a complete modern definition inventory

From Middle English bylawe, bilawe, partly from Old English bīlage (“bylaw”) and partly from a variant of Middle English byrelawe, birlawe, from Old Norse býjar (“town's; settlement's”) + lǫg (“laws; jurisdiction”). Byrlaw is attested earlier in English but is unattested in Old Norse and the cognates in Scandinavian languages follow the development of bylaw: Danish bylov (“municipal law”), Swedish bylag and byalag.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
