Forms

slakr adj (feminine slǫk, neuter slakt)[1]

Etymology

It is inherited from Proto-Germanic *slakaz (“slack”),[2][3][4] like Old English slæc, Old Saxon slak (“slack, cowardly”) and Old High German slah.[3][5]

Kroonen describes it as an o-grade adjective to a scarcely attested root and compares Ancient Greek λαγαρός (lagarós, “slack, thin”) and, with a query, Old Irish lacc (“slack”);[3] Wiktionary sets up Proto-Indo-European *slogos and adds Latin laxus (“loose”), which Hellquist also names.[2][6] Köbler gives Pokorny's Proto-Indo-European *slēg- (“slack, weary”).[5]

Earliest recorded meaning

The only old record is in a stanza attributed to Bragi, in his Ragnarsdrápa on Þórr's fishing, preserved in Snorri's Edda: vaðr vilgi slakr “the line not at all slack”.[7][1][8]

Semantic evolution

Old Norse has the word only in this verse, which Hægstad and Torp mark as poetic,[9][10] but Cleasby and Vigfússon found it very frequent in the Icelandic of their day, with slá slǫku við “to slacken one's effort”.[1] The Icelandic descendant slakur also means “weak, poor, inferior”.[11][12] It continues as Swedish slak, first recorded in Old Swedish as a rendering of Latin discinctus.[6]
