Reconstruction

Ringe and Taylor reconstruct *lagu for Proto-West Germanic,[1] and Wiktionary has the same form.[2]

Etymology

It is inherited from Proto-Germanic *laguz (“water, sea”),[1] which Ringe and Taylor set up for Proto-Northwest Germanic on the evidence of Old Norse lǫgr, Kroonen cites by its stem *lagu-, and Orel writes *laʒuz.[1][3][4] In Old English the *a was first fronted, *lægu, and then retracted before the u of the next syllable, as in the other u-stems, giving lagu.[1]

Morphology

A masculine u-stem.[5][6][3]

Evidence

Only Old English and Old Saxon record the word.[7][8] Old English has lagu "sea, water, flood",[5] and Old Saxon has lagu once, as the name of a rune in the Abecedarium Nordmannicum of 829–849,[7][9] besides the Heliand compounds lagustrōm "flood of water" and lagulīthand "seafarer".[10][11] Ringe and Taylor compare Old Saxon lagustrōm with Old English lagustrēam.[1] Old Frisian, Old Dutch and Old High German have no record of it: Köbler sets up only an unattested Old High German *lagu after the Old Saxon word,[8] and Wiktionary reconstructs Old Frisian *lage.[2]

The oldest record may be the man's name ⟨laguþewa⟩ on the shield-handle mount of Illerup III in Jutland, which Düwel, Nedoma and Oehrl date to around or shortly after 200.[12] They interpret it as a West Germanic name Laguþewa in the nominative singular, whose first element belongs with Old Saxon lagu- and Old English lagu.[13] Looijenga also reads a personal name with a first element ⟨lagu-⟩ "sea, water", and rejects a connection with the word for "law" because of the composition vowel -u-.[14] In the inscription of Pforzen I, Seebold reads two runes as concept runes for *lagu- "water, sea, lake" and *tīwa- "god", a compound "lake-god".[15]

Meanings

  1. water, sea[1][2]

Kroonen glosses the Old English and Old Saxon words as "lake".[3]

Reflexes

  • Old English: lagu (“sea, water, flood”)[5]
  • Old Saxon: lagu (“sea, lake; name of a rune”)[7][9]
