Forms

lag n (genitive lags, plural lǫg) (strong a-stem)[1]

Etymology

It is inherited from Proto-Germanic *lagą (“situation; law; settled amount”),[1] made to the root of liggja and leggja, and meant first “what lies or is laid”.[2][3] Its West Germanic relatives are Old Saxon aldarlagu (“allotted lifetime”) and gilagu (“destiny”).[2][4] The root is Proto-Indo-European *legʰ- (“to lie”).[1] Torp compares Ancient Greek λόχος (lókhos, “ambush”), literally “the lying”,[2] and Falk and Torp λέχος (lékhos, “bed”).[5]

Ásgeir Blöndal Magnússon separates two older shapes: the sense “fellowship” from a form with the prefix *ga-, like German Gelage, and the plural lǫg “decrees, fate” perhaps from a form like Old English gelagu.[3]

Earliest recorded meaning

The word is first found on the Swedish inscription Hs 7, of the 800s, where a penalty rises each time: at fyrsta lagi, at ǫðru lagi, at þriðja lagi “the first time, the second time, the third time”.[6][7] In manuscripts ONP's first dated records are of 1200, in the Icelandic Homily Book, with the plural for the Law of Moses: gaf goþ lǫg moisi a fialle “God gave Moses the law on the mountain”.[8]

Semantic evolution

Cleasby and Vigfússon start from “layer” and set out the senses “due place, right position”, “fellowship”, “living together”, “market price” and “thrust (with a weapon)”.[9] Phrases with í … lagi gave adverbs of degree and manner, such as í ǫðru lagi “on the other hand” and í mesta lagi “to the greatest degree”.[10][11] In poetry lag is also the form of a verse, the metre.[12][11]

The plural lǫg became the word for “law” and for a law community.[8][13] It was borrowed as Old English lagu in the late Old English period, and through it English has law.[13][14]
