Sight
for “multitude” is not an Americanism, but good Old English. Thus, in Morte dʹArthur, the word is not unfrequently so employed; and the high-born dame, Juliana Berners, lady prioress in the fifteenth century of Sopwell nunnery, speaks of a bomynable syght of monkes (a large number of friars).
“Where is so huge a syght of mony.”—Pulsgrave: Acolastus (1540).
