Jessica

First used by William Shakespeare in Merchant of Venice in the early 17th century, probably from Hebrew יִסְכָּה (yiská, “Iscah in Genesis 11:29, Jescha in the Wycliffe version”), a proper name meaning "he will see/behold/look for", the 3ms imperfect form of a verb ultimately from the root ס־כ־ה (s-k-h), itself an alternative form of the root שׂ־כ־ה (ś-k-h), both of which mean "to see, behold, look for".

By folk etymology seen as an elaborate form of Jessie, from Jane.
