Word Origin & History

kos 
measure of distance in India (about 2 miles), from Hindi kos, from Skt. krosah, lit. "a call, a shout;" thus, "distance within which a man's shout can be heard."

romaine 
1907, from Fr. romaine (in laitue romaine, lit. "Roman lettuce"), from fem. of O.Fr. romain "Roman," from L. Romanus "Roman." Perhaps so called because of the lettuce's introduction into France (by Bureau de la Rivière, chamberlain of Charles V and VI) at the time of the Avignon papacy (1309-77).
