bylaw

• byrlaw (obsolete)
• by-law
• bye-law, byelaw

From Old Norse by (“town; settlement”) + lag (“[something] laid down; law; fellowship”), apparently a variant of Middle English byrlaw, 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.[1]
