seise

Etymology

From Middle English seisen, from Old French seisir (“to put in possession of", "to take possession of”), from Early Medieval Latin sacīre, from Frankish *sakjan (“to sue, bring a legal charge against”), from Proto-Germanic *sakōną (“to charge, seek legal action against”), from Proto-Indo-European *seh₂g- (“to track”). Cognate with Old High German sahhan (“to argue, scold”), Old English sacian (“to strive, contend”). More at sake.
