Etymology
It is inherited from Proto-West Germanic *slak, from Proto-Germanic *slakaz (“slack”).[1][3] Its cognates are Old Norse slakr, Old Saxon slak (“slack, cowardly”) and Old High German slah.[3][4] Heidermanns finds the adjective only in North and West Germanic.[5]
Kroonen calls it an o-grade adjective to a root Proto-Indo-European *sleg- that is only marginally attested, and compares Ancient Greek λαγαρός (lagarós, “slack, thin”) and, with doubt, Old Irish lacc (“slack”).[3] Holthausen adds Latin laxus (“loose”) and langueō (“to be faint”).[6] Köbler refers it to the same root, which he sets up with a long vowel and the meaning “slack, faint”.[7] Orel sets it up as *slakwaz and derives it from a verb meaning to slacken.[8]
Earliest recorded meaning
The adjective is first recorded in the Pastoral Care (Hatton 20, 890×897), where the ruler should be “ne to stræc on ðære lare, ne to slæc on ðære mildheortnesse” (“neither too strict in his teaching nor too slack in his mercy”).[9][10] It renders Latin “remissa” there, of mercy that is lax.[2]
Semantic evolution
Bosworth and Toller divide the senses between persons and things.[2] Of persons it means idle and lazy, glossing Latin “piger”, “reses” and “lentus”, then careless or remiss in duty, and in glosses also weak or ill, rendering “aeger”.[2][7] Ælfric's homilies have the wicked and slothful servant of the parable, yfela þeowa and sleac.[2] Of things it is used of slow, gentle movement, of a sleep that makes one sluggish, of service done without effort, and of a lax way of life.[2]
Middle English slak meant indolent.[11] From about 1300 it was also used of things that are loose and not taut,[11] and it survives as English slack.[11]

Usage notes
Bosworth and Toller count the sleac of Beowulf (line 2187) as this word, but Klaeber treats slēac “slow, slothful” as a different word, not related to slæc.[2][12]
