| Meaning | Coined by William Shakespeare for his 1596 play The Merchant of Venice, where it belongs to Shylock's daughter — likely based on the biblical name Iscah, also spelled Jescha/Jischa in some translations of Shakespeare's time. | Likely derives from a Hebrew word meaning 'weary, grieved'; an alternative theory suggests a connection to Akkadian 'littu' ('cow'). In the Old Testament, Leah was Jacob's first wife. |
