How did it exist? I am glad I was not born before tea.
Sidney Smith (1711-1845)
Jug. Vessel. Pet-form of of Joan, also of Judith. So also Middle English jobbe, jubbe, used by Chaucer for drinking vessel, is probably from Job, often Jubbe, Juppe in Middle English, whence modern names Jubb, Jupp. It is even possible that jug is altered on the female name from the earlier jub. The jug, or stone-jug, i.e. gaol is from thieves cant.
