Pronunciation

Forms

sacu f (strong ō-stem; genitive singular sace, nominative plural saca)[1]

Etymology

It is inherited from Proto-Germanic *sakō (“lawsuit, quarrel”), a noun made from the strong verb *sakaną (“to charge”), whose Old English form is sacan.[1][2][3] Its cognates are Old Norse sǫk (“lawsuit, charge”), Old Frisian seke, Old Saxon saka and Old High German sahha.[2][3][4] Köbler also names Proto-Germanic *sakjō, which Gothic 𐍃𐌰𐌺𐌾𐍉 (sakjō, “dispute”) continues, and traces both to the root Proto-Indo-European *seh₂g- (“to seek out”).[5][1] Kroonen derives the verb from the same root and compares Old Irish saigid (“seeks to reach, claims”) and Latin sāgus (“prophetic”).[6]

In the oblique cases the noun often has forms with ⟨sæc-⟩, which Klaeber refers to the related noun sæċċ.[7][8]

Earliest recorded meaning

The first dated record is in the Old English Orosius (Tollemache manuscript, s. x¹ or x²/⁴): Caligula complained þæt þær þa næs swelc sacu swelc þær oft ær wæs “that there was then no such strife as there often had been before”.[9][10][11]

Semantic evolution

The first sense is strife, dispute and sedition: in the Old English Genesis the quarrel between the herdsmen of Abraham and Lot is a sacu.[11] In the poetry it is fighting and war: Beowulf has sacu restan “strife shall rest” between the Geats and the Danes.[8] It also means affliction and persecution, and sin or guilt.[11][7] In the laws it is a lawsuit or charge, and in the formula sacu and sōcn the right of holding a court together with its profits, the “sake and soke” of later legal language.[12][7] LangScape records it in the charters in the sense “jurisdiction”.[13]

The word lived on as Middle English sake “strife, dispute, legal action”, the source of sake in for the sake of.[14][15]
