As defined by the Cleasby & Vigfusson Old Norse to English dictionary:
- m. pl. ‘Oath-sibs,’ the name of a confederation of kinglets in southern Norway: whence the name Eiðsifja-lög, m. pl. a collection of laws in N. G. l. i. The word is differently spelt, Heiðsifjar, Heiðsævi, etc. But the syllable eið- may be derived from eið, an isthmus, because their parliament was held on an isthmus, Eid, now called Eidsvold; vide Munch.
