(comparative more sackless, superlative most sackless)
Though otherwise dated, the word sackless is still used in translations of the Old Norse / Old Icelandic sagas and related contexts.
From Middle English sakles, sacless (“innocent”), from Old English saclēas (“free from charge, innocent, safe”), from Proto-Germanic *sakalausaz (“free from accusation”), equivalent to sake + -less. Cognate with Danish sagesløs (“blameless”), Swedish saklös (“blamesless”), Icelandic saklaus (“innocent”). More at sake, -less.
