saisir

From Old French seisir (whence English seize), from Medieval Latin saciō, sacīre (“lay claim to, take seisin”), from Frankish *sakjan (“to sue, litigate; accuse”).[1][2] Compare Old English sacian (“to strive, brawl”), Faroese saka (“to hurt; accuse”), obsolete English sake (“strife”).

Alternatively from Old High German *sazjan[3] and thus cognate to German setzen (“to set”) and Gothic 𐍃𐌰𐍄𐌾𐌰𐌽 (satjan).
